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)

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
