Add CLI implementation and MVP performance review
...
- Implement functional CLI with clap argument parsing
- Add directory scanning and metadata extraction at startup
- Fix filesystem.rs to store tokio Handle for async/sync bridge
- Fix flake.nix with LD_LIBRARY_PATH for libfuse3
- Add MVP performance review with real-world benchmark results
Benchmarks show:
- Mount time: 8ms (target <500ms)
- Throughput: 2-3 GB/s (target >500 MB/s)
- Identifies critical gap: incomplete file caching (only ~2MB per file)
- Identifies missing CDC chunking per architecture spec
