Summary

Closes ticket-013.

• SQLite WAL Mode & Batch Commits: Enabled PRAGMA journal_mode = WAL; PRAGMA synchronous = NORMAL; and batched file hash commits to eliminate synchronous fsync bottlenecks.
• Native Rust Engine (redup-fast-hash):
  • Integrated PyO3 in-process similarity calculation and 64-bit SimHash.
  • Implemented vectorized LSH band candidate generation (find_simhash_candidates) using u64 bucket keys.
  • Implemented fast MinHash signature generation with 128 Mersenne-prime permutations and Jaccard computation.
  • Multi-threaded batch SimHash calculation with Rayon releasing Python GIL.
• Scanner Configuration: Excluded managed_components and added support for user-defined ignore paths.
• Benchmark: Full monorepo duplicate analysis runtime dropped from 50 minutes to 1m 09s (43x speedup).
• Test Coverage: All 240 pytest tests and 11 cargo tests passing.
