gamertan db9059e2fc feat: optimization refactor, test suite, and dependency cleanup 
Refactored the application to improve performance, maintainability, and binary size.

Key Changes:
- **Core Algorithm**: Switched to a parallel, single-pass tree construction algorithm for O(N) traversal.
- **Architecture**: Extract core logic from `main.rs` to `lib.rs` to enable unit testing.
- **Testing**: Added comprehensive unit tests and integration tests (`tests/cli.rs`) covering CLI arguments and output formats.
- **Benchmarking**: Added `criterion` benchmarks for performance tracking.
- **Dependencies**:
  - Removed `walkdir` (logic replaced by `ignore` + custom tree).
  - Removed `humansize` (consolidated to `byte-unit`).
  - Replaced `chrono` with lightweight `time` crate.
  - Removed unused `atty`.
- **Reporting**: Optimized CSV and JSON output for correctness and zero-copy performance.
- **Documentation**: Updated CHANGELOG.md and bumped version to 0.2.0.

Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.2.0] - 2026-01-22

Changed

  • Refactored core traversal logic to a single-pass, in-memory tree construction algorithm. This visits every file exactly once, replacing the previous O(N \times Depth) behavior with O(N).
  • Switched default CSV output to use the csv crate for robust escaping (fixes issues with filenames containing commas).
  • Optimized JSON output to use zero-copy serialization, improving performance and memory usage.

Added

  • Added MANUAL.md with comprehensive usage documentation.
  • Added comprehensive test suite (unit and integration tests).
  • Added performance benchmarks using criterion.

Removed

  • Removed walkdir dependency (replaced by ignore::WalkBuilder for all traversal).
  • Removed humansize (consolidated to byte-unit).
  • Removed chrono (replaced with lightweight time).
  • Removed atty (unused).

[0.1.0] - 2026-01-22

Added

  • Core directory traversal and size calculation logic.
  • Parallel processing using rayon for high performance.
  • Rich table output format using comfy-table with colored entries.
  • Recursive depth control via -d/--depth.
  • Minimum size filtering via -m/--min-size.
  • Multi-column sorting support (--sort).
  • Relative path display by default, with -f/--path-full override.
  • "Total size" summary with dual units (Binary/Decimal) and block counts.
  • Concurrency control via -j/--threads.
  • .gitignore and .ignore file support via -i/--ignore.
  • Multiple output formats: Text (Table), CSV, JSON (--format).
  • Save to file functionality with auto-naming (--save).
  • Shell completion generation (--completions).
