Watcher doesn't have access to file_id; indexer handles fallback
via metadata lookup or remove_by_path

- Fix delta.rs unused imports

Oracle fixes applied:
- SMB retry_on_disconnect for ENOTCONN (errno 107)
- session_token Debug shows [REDACTED] when Some, None otherwise
- NFS/SMB health checks wrapped with tokio::time::timeout(5s)

102 tests pass, 0 warnings.

Alexander d5ef68c9c9 Implement Week 6 Origin Federation with Oracle fixes 
New files:
- musicfs-core/src/config.rs: Config, OriginConfig, HealthConfig
- musicfs-origins/src/registry.rs: OriginRegistry with watch cleanup
- musicfs-origins/src/router.rs: Priority router with (priority, latency) ordering
- musicfs-origins/src/health.rs: HealthMonitor with per-origin-type thresholds
- musicfs-origins/src/failover.rs: FailoverExecutor with NFR-7.3 backoff

Oracle fixes applied:
- Per-OriginType threshold: Local=1, Remote=3 (check_one uses threshold_for)
- AllOriginsUnhealthy event: Added to events.rs, emitted in select_with_fallback
- Unified OriginType: Removed duplicate from traits.rs, use musicfs_core::OriginType
- Watch handle cleanup: Tracked and dropped on unregister()
- Retry delays: 100ms, 500ms, 2000ms (NFR-7.3 compliant)

Tests: 91 pass (+20 new)

- Add CdcChunker using FastCDC v3 (16KB/64KB/256KB chunks)
- Add DeltaDetector with scan_origin() returning ScannedFile (no FileId assignment)
- Add OriginWatcher with inotify and 200ms debounce using tokio::spawn
- Fix LocalOrigin::read() to loop until all bytes read
- Add read_full() method to Origin trait
- Add mtime field to ChunkManifest
- Update ContentFetcher to use CDC chunking

Alexander 7ad554f8d5 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
