feat: v0.2.0 - Performance optimization and distribution pipeline

- Implemented multi-threaded directory traversal using ignore::WalkParallel
- Added dynamic thread allocation for balanced CPU utilization
- Refactored core logic to single-pass, in-memory tree construction (O(N))
- Added --compare, --units, and --precision flags
- Established SCM-neutral distribution pipeline (Makefile, release.sh, Homebrew)
- Comprehensive updates to README.md, MANUAL.md, and CHANGELOG.md
- Decoupled from SCM-specific workflows
