Phil Skentelbery 1b51c82656 feat: Implement v1.4.0 Phase 1 - Large Image Support ...

Implement tiered resize strategy for large images per v1.4.0 design:

Changes:
- Increase MAX_FILE_SIZE from 10MB to 50MB
- Add MAX_OUTPUT_SIZE constant (10MB target after optimization)
- Add MIN_QUALITY and MIN_DIMENSION constants
- Add get_optimization_params() for tiered strategy:
  - <=10MB: 2048px max, 95% quality
  - 10-25MB: 1600px max, 90% quality
  - 25-50MB: 1280px max, 85% quality
- Update optimize_image() signature to return 4-tuple (img, w, h, bytes)
- Implement iterative quality reduction if output >10MB
- Add animated GIF detection and size check in validate_image()
- Update save_media() to use new optimize_image() return value
- Fix GIF format preservation during optimization
- Update tests to match new optimize_image() signature

All existing tests pass. Ready for Phase 2 (Image Variants).
