Implement Week 4 CAS store with chunk deduplication and LRU eviction

- Add musicfs-cas crate: CasStore, ChunkHash, FileReader, ChunkManifest
- Add LruEviction policy to musicfs-cache for cache size management
- Integrate FileReader into FUSE filesystem for actual file reads
- Use xxHash64 for content hashing, sled for index, msgpack serialization
- Default cache path: ~/.cache/musicfs/chunks/ with 256 subdirs sharding
- 20 new tests (14 CAS unit + 3 integration + 3 eviction), 54 total

Add development plan and Oracle-validated weekly plans (Weeks 1-3)

development-plan.md (master plan):
- 11-week implementation broken into 4 phases
- 11 Rust crates with dependency graph
- Per-week deliverables, tests, exit criteria
- Deferred requirements (FR-21, FR-22) with rationale

plans/week-01-foundation.md:
- Workspace setup, core types, FUSE skeleton, local origin
- Origin trait with watch() method (arch 4.3.4)
- EventBus with FileAccessed event (FR-18.1)
- All EROFS handlers for read-only enforcement (FR-4.1-4.5)

plans/week-02-metadata.md:
- symphonia metadata extraction (FR-6.1-6.5)
- SQLite schema matching architecture 4.3.6 exactly
- Column names: track/disc (not track_number/disc_number)
- Hash columns as TEXT (hex-encoded, not BLOB)
- Added idx_files_real index (FR-7.3)

plans/week-03-virtual-tree.md:
- Path resolver with $var syntax (arch 4.3.1)
- Template vars: $artist, $album, $title, $track, $year, $disc, $genre, $format, $format_upper
- RefreshPolicy struct for FR-9.3 (TTL-based refresh)
- force_refresh() method for FR-9.4 (signal/API refresh)

All plans Oracle-validated against architecture.md and requirements.md
