agatha f953c88984 Feat: Pre-generate WebP thumbnails on upload for faster library load
- Add Pillow dependency and thumbnail.py with generate_thumbnail() — produces
  WebP ≤400px, preserves aspect ratio, never upscales, handles GIF frame 0
- Alembic migration 002 adds nullable thumbnail_key column to images table
- Upload route generates thumbnail via asyncio.to_thread (non-blocking),
  stores at {hash}-thumb; failure is tolerated and upload succeeds with null key
- New GET /api/v1/images/{id}/thumbnail endpoint: serves WebP thumbnail or
  falls back to original for pre-feature images; ETag + immutable cache headers
- Delete route cleans up thumbnail storage object alongside original
- Library grid switches from /file to /thumbnail for all image src bindings
- 59 tests passing (46 existing + 13 new across unit, upload, serving, delete)

  • Focused on user value and business needs
  • Written for non-technical stakeholders
  • All mandatory sections completed

Requirement Completeness

  • No [NEEDS CLARIFICATION] markers remain
  • Requirements are testable and unambiguous
  • Success criteria are measurable
  • Success criteria are technology-agnostic (no implementation details)
  • All acceptance scenarios are defined
  • Edge cases are identified
  • Scope is clearly bounded
  • Dependencies and assumptions identified

Feature Readiness

  • All functional requirements have clear acceptance criteria
