4.4.26: Static Linux Builds, Memory-Aware Batching & Cross-Compilation Fixes

This release includes critical build system improvements and enhanced batching capabilities for more predictable resource usage.

### Cross-Compilation & Static Builds
- Fixed cross-compilation for Linux by introducing architecture-specific `CGO_CFLAGS` (x86_64-linux-gnu and aarch64-linux-gnu), ensuring correct header resolution during static linking.
- Enabled fully static Linux binaries using musl, producing self-contained executables with no external runtime dependencies.

### Memory-Aware Batching (New Feature)
- Added `--batch-mem` CLI option to control batching based on estimated memory usage (e.g., 128K, 64M, 1G), in addition to size-based limits.
- Introduced configurable min/max batch sizes and memory thresholds, with conservative memory estimation per sequence to avoid over-allocation.
- Implemented intelligent flushing logic that triggers when *either* byte or record count limits are exceeded, ensuring predictable memory behavior.
- Improved garbage collection after large batch discards to reduce memory pressure during large-scale processing.

### Build & Toolchain Improvements
- Updated Go toolchain to 1.26.1 and bumped key dependencies (e.g., golang.org/x/net v0.38.0).
- Enhanced build error reporting: logs are now displayed before cleanup on failure.
- Fixed Makefile quoting for `LDFLAGS` containing spaces.
- Updated install script to properly configure GOROOT, GOPATH, and GOTOOLCHAIN, with added progress feedback for downloads.

All batching behavior is backward-compatible and uses sensible defaults (128 MB memory, min: 1 record, max: 2000 records) to ensure smooth upgrades.

-# Objective
-
-Fully document OBITools (version 4, written in Go) in English, using a 4‑phase incremental pipeline.
-
-You **MUST** use the available MCP servers:
-
-- `cclsp` – exact definitions, references, diagnostics  
-- `jcodemunch` – code indexing, symbol extraction  
-- `treesitter` – AST and CLI parsing  
-- `context7` – external documentation  
-
-All tool calls must follow the exact API described in the MCP server documentation. If a required tool is unavailable, you **MUST** log the error and stop execution.
-
-### Tool call format (CRITICAL)
-
-Tool calls **MUST** use this exact XML format — no spaces inside the angle brackets:
-
-```
-<function=tool_name>
-{"param": "value"}
-</function>
-```
-
-**FORBIDDEN** — these variants will cause parse errors and must NEVER be used:
-- `< function=tool_name >` (spaces around the tag name)
-- `< function = tool_name>` (spaces around `=`)
-- `<function = tool_name>` (space before `=`)
-
-The opening tag is `<function=tool_name>` with **zero spaces** inside `<` and `>`.
-
----
-
-# Global rules
-
-** You are not allowed to read twice the same file in a row. **
-
-## Language
-
-- All generated documentation **MUST** be in English.  
-- If an existing documentation file is in French:  
-  1. Translate it to English  
-  2. Save the original as `.fr.md` **before** overwriting  
-  3. Write the new English version  
-
----
-
-## Execution mode (STRICT)
-
-You are operating in **STRICT TOOL MODE**:
-
-- If a file must be written, you **MUST** use the `Shell` tool.
-- You **MUST NOT** read entire directory listings into memory.
-- You **MUST** work with **one item at a time** using a simple text file as a task queue.
-
-### Reading files before writing
-
-- **Before writing to an existing documentation file**, you must first read it using the `Read` tool.
-- **When documenting a single Go source file**, you only need to read that one file (plus up to 4-5 helper files if needed for context).
-- Do NOT read the entire codebase - only what is necessary to document the current file.
-
----
-
-### Rules
-
-- Always write the **full** file (no partial updates).  
-- Paths are relative to the project root; directories are created implicitly.  
-- Content must be valid UTF‑8; use `\n` line endings.  
-- Do **not** wrap content in backticks.  
-
----
-
-## Progress tracking: task queue files
-
-We use **line‑oriented task files** to avoid loading large lists into memory. Each phase has its own task file:
-
-- `docs/todo/phase1.txt` – list of Go files (one per line) to document.  
-- `docs/todo/phase1bis.txt` – same list, but after phase1 is done.  
-- `docs/todo/phase2.txt` – list of packages.  
-- `docs/todo/phase3.txt` – list of tools.
-
-**How it works:**
-
-1. At the start of a phase, if the task file does not exist, it is created by scanning the codebase once (Phase 0 or Phase X init).  
-2. **Each run of the LLM processes only the first line of the task file.**  
-3. After processing the item (success or permanent failure), the line is removed from the task file.  
-   - On success, the line is deleted (no extra sentinel file needed).  
-   - On transient failure (retry < 3), we keep the line but increment a retry counter stored in a separate file.  
-   - On permanent failure (retry ≥ 3), we move the line to a `failed.txt` file and log the error.  
-4. The LLM then exits (or continues if the task file is still non‑empty, but it must never load more than one line).
-
-This way, the LLM’s context never holds more than a single task at a time.
-
-### Retry mechanism
-
-For each item (e.g., `internal/align/align.go`), we maintain a retry counter in:
-
-- `docs/retry/phase1/internal/align/align.go.count`
-
-If the file does not exist, retries = 0.  
-Each time processing fails, we increment the counter (write the new number).  
-If after increment the counter < 3, we keep the line in the task file.  
-If counter reaches 3, we **remove the line from the task file**, add it to `docs/failed/phase1/internal/align/align.go.failed` (just a marker), and log the error.
-
----
-
-## Documentation quality requirements (CRITICAL)
-
-Documentation MUST NOT be superficial. For each documented element (file, function, struct, package):
-
-###  You MUST explain:
-
-- what it does
-- why it exists (context, problem solved)
-- how it is used
-- assumptions and preconditions
-- possible edge cases
-
-### Forbidden patterns
-
-- Vague phrases like “This function handles…”, “Utility for…”, “Helper function…”.
-- Generic descriptions that could apply to any project.
-
-### Required content per element type
-
-- Functions:
-  - Purpose
-  - Parameter meaning
-  - Return values
-  - Notable behaviour (panic conditions, side effects, concurrency)
-- Structs:
-  - Role in the system
-  - Meaning of key fields
-- Files:
-  - Role within the package
-  - Interactions with other files
-
-### Anti‑generic rule
-
-If the description could apply to any project, it is INVALID. You MUST include domain‑specific context (bioinformatics, sequence processing, etc.) and concrete behaviour.
-
-### Quality validation
-
-Before marking an item as done (i.e., creating the .done sentinel), you MUST perform a self‑validation:
-
-- Check that all required sections are present.
-- Verify that no forbidden patterns remain.
-
-If validation fails, increment the retry counter and keep the item pending.

-# Phase 0: Initialization
-
-1. Ensure required directories exist: `docs/todo`, `docs/retry`, `docs/failed`, `docs/phase1`, `docs/phase2`, `docs/phase3`.  
-2. **If `docs/todo/phase1.txt` does not exist**:  
-   - Use `find pkg -name "*.go" ! -name "*_test.go" ! -path "*/cmd/*"` to list all Go files (excluding tests and main.go).  
-   - Write the list (one relative path per line, e.g., `internal/align/align.go`) to `docs/todo/phase1.txt`.  
-3. Do the same for phase2 and phase3 later when those phases start.  
-4. **No other state is stored.**
-
----
-
-# Phase 1: File documentation
-
-**Processing rule:**
-- Read the **first line** of `docs/todo/phase1.txt` (using `head -n 1`).  
-- If the file is empty, Phase 1 is complete → proceed to Phase 1bis initialization.  
-- Otherwise, process that single file.
-
-**Processing a file:**
-
-1. Let `relpath` be the line content (e.g., `internal/align/align.go`).  
-2. Check if a permanent failure marker exists at `docs/failed/phase1/${relpath}.failed`. If yes, remove the line from the task file and skip (line will be deleted). 
-3. If the documentation file `docs/phase1/${relpath}.go.md` exists go directly to its validation (step 6).
-4. Otherwise, generate documentation for that file (using MCP tools as before).  
-5. Write the documentation to `docs/phase1/${relpath}.go.md`.  
-6. Validate quality.  
-7. If validation succeeds:  
-   - Remove the line from the task file.  
-   - Remove any retry counter file for this item.  
-   - (No sentinel needed; the removal from todo indicates completion.)  
-8. If validation fails:  
-   - Increment retry counter:  
-     - If `docs/retry/phase1/${relpath}.count` does not exist, set to 1.  
-     - Else read it, add 1, write back.  
-   - If new counter >= 3:  
-     - Remove line from task file.  
-     - Create `docs/failed/phase1/${relpath}.failed`.  
-     - Log error.  
-   - If new counter < 3:  
-     - Keep the line in the task file (do nothing, it stays as first line for next run).  
-9. **Exit** (or stop if this was a single run). The next invocation will read the first line again (same if retry, or next if removed).
-
-**Important:**  
-- Do **not** read more than one line.  
-- Do **not** attempt to process multiple items in one run.  
-- The LLM should finish after handling one item.
-
----
-
-# Phase 1bis: Review and harmonization
-
-When Phase 1 is complete (i.e., `docs/todo/phase1.txt` empty), we initialize `docs/todo/phase1bis.txt` with the same list of files (the ones that succeeded).  
-But note: we need to know which files were successfully documented. Since we removed lines from `phase1.txt` on success, we need a record. The simplest is to reuse the same list but we can generate it by listing the existing `.go.md` files in `docs/phase1/` (since every successful file has a `.go.md`).  
-Thus, Phase 1bis initialization:
-
-- If `docs/todo/phase1bis.txt` does not exist, create it by listing all `.go.md` files under `docs/phase1/`, stripping the `docs/phase1/` prefix and the `.go.md` suffix, and writing the relative path (same format as phase1).  
-
-Then processing is identical to Phase 1, but using `docs/todo/phase1bis.txt` and output is overwriting the same `.go.md` files (with improvements). Retry counters go in `docs/retry/phase1bis/`.
-
----
-
-# Phase 2: Package documentation
-
-When Phase 1bis is complete (`docs/todo/phase1bis.txt` empty), initialize `docs/todo/phase2.txt`:
-
-- List all packages: unique directories under `pkg/` that contain at least one `.go` file and are not tools.  
-- Write each package identifier (e.g., `align`, `internal/align`) as a line.
-
-Processing: read first line, generate `docs/phase2/<package>.md`, validate, remove line on success, retry logic in `docs/retry/phase2/`.
-
----
-
-# Phase 3: Tool documentation
-
-When Phase 2 complete, initialize `docs/todo/phase3.txt`:
-
-- List all directories under `cmd/` that contain a `main.go`. Write each tool name as a line.
-
-Processing: read first line, generate `docs/phase3/<tool>.md`, validate, remove line on success, retry logic in `docs/retry/phase3/`.
-
----
-
-# Finalization
-
-When all task files are empty and no pending phases, generate `docs/README.md` by:
-
-- Listing all package docs (files in `docs/phase2/`) and linking.  
-- Listing all tool docs (files in `docs/phase3/`) and linking.  
-
-Write using `Shell`.
-
----
-
-# Execution flow summary
-
-1. **Phase 0**: Create directories and initial `todo/phase1.txt` if missing. Exit.  
-2. **Phase 1**:  
-   - If `todo/phase1.txt` exists and non‑empty → process first line.  
-   - Else → move to Phase 1bis initialization.  
-3. **Phase 1bis**:  
-   - If `todo/phase1bis.txt` does not exist → create from successful phase1 docs.  
-   - If non‑empty → process first line.  
-   - Else → move to Phase 2 initialization.  
-4. **Phase 2**: similar.  
-5. **Phase 3**: similar.  
-6. **Finalization**: generate README.
-
-The LLM should be invoked repeatedly (e.g., by a scheduler) until all phases are done. Each invocation processes exactly one item.
-
----
-
-# Important reminders
-
-- Always call `Shell` to write files; never output content in plain text.  
-- Validate quality before removing a line from the task file.  
-- Log all failures to `docs/error.log` in JSON lines format.  
-- If any MCP tool fails, treat as failure and increment retry counter.  
-- Never read more than one line from a task file in a single run.

-# DNA Scoring and Matching Utilities in `obialign`
-
-This module provides low-level utilities for computing nucleotide alignment scores using probabilistic and bit-encoded representations.
-
-- **Bit Encoding**: Nucleotides are encoded in 4-bit groups (e.g., `A=0b0001`, `C=0b0010`, etc.), enabling efficient bitwise comparison.
-- **`_MatchRatio(a, b)`**: Computes a normalized match ratio between two encoded bytes based on shared bits:
-  `ratio = common_bits / (bits_in_a × bits_in_b)`.
-- **`_FourBitsCount`**: Precomputed lookup table for Hamming weight (popcount) of 4-bit values.
-- **Log-space Arithmetic**: Helper functions (`_Logaddexp`, `_Logdiffexp`, `_Log1mexp`) ensure numerical stability in probabilistic computations.
-- **Phred-scaled Quality Integration**:
-  `_MatchScoreRatio(QF, QR)` derives log-odds match/mismatch scores from Phred quality values (`QF`, `QR`), modeling sequencing error probabilities.
-- **Precomputed Matrices**:
-  - `_NucPartMatch[i][j]`: Match ratios for all nucleotide pairs (from 4-bit codes).
-  - `_NucScorePartMatchMatch/Mismatch[i][j]`: Integer-scaled match/mismatch scores (×10) for quality pairs `(i, j)` in `[0..99]`.
-- **Thread-Safe Initialization**: `_InitDNAScoreMatrix()` ensures one-time, synchronized initialization of all scoring tables via a mutex.
-
-Designed for high-performance alignment kernels where speed and numerical robustness are critical.
