- Remove redundant validation logic in login handler
- Consolidate session token generation into a single utility function
- Update error handling to use consistent HTTP status codes
- Add `hash` field to MmerItem for stable, randomized minimizer ordering
- Introduce hash_mMER() using mix64 with XOR seed to avoid fixed points (e.g., poly-A/T)
- Remove is_degenerate() and minimizer_worse(), simplifying comparison to hash-only
- Update push logic: compare hashes instead of canonical values with degeneracy checks
- Remove `entropy.rs`, `minimizer.rs` and `window.rs`; consolidate logic into new module
- Introduce unified state management in RollingStat with incremental entropy tracking and canonical minimizer computation via monotone deque
- Update SuperKmerIter to use RollingStat instead of separate components, simplifying iteration and state transitions
- Add `*.fasta` to .gitignore for generated FASTA outputs
