4.4.28: Static Linux Builds, Memory-Aware Batching, and Build Stability

Browse Source 
This release focuses on improving build reliability, memory efficiency for large datasets, and portability of Linux binaries.

### Static Linux Binaries
- Linux binaries are now built with static linking using musl, eliminating external runtime dependencies and ensuring portability across distributions.

### Memory-Aware Batching
- Users can now control memory usage during processing with the new `--batch-mem` option, specifying limits such as 128K, 64M, or 1G.
- Batching logic now respects both size and memory constraints: batches are flushed when either threshold is exceeded.
- Conservative memory estimation for sequences helps avoid over-allocation, and explicit garbage collection after large batch discards reduces memory spikes.

### Build System Improvements
- Upgraded to Go 1.26 for improved performance and toolchain stability.
- Fixed cross-compilation issues by replacing generic include paths with architecture-specific ones (x86_64-linux-gnu and aarch64-linux-gnu).
- Streamlined macOS builds by removing special flags, using standard `make` targets.
- Enhanced error reporting during build failures: logs are now shown before cleanup and exit.
- Updated install script to correctly configure GOROOT, GOPATH, and GOTOOLCHAIN, with visual progress feedback for downloads.

All batching behavior is non-breaking and maintains backward compatibility while offering more predictable resource usage on large datasets.
