## Summary
Adds 12 tests for `src/scripts/metadata/avif.ts`, raising line coverage
from **2.3% → 90.4%** (statements 88.5%, functions 93.3%).
## Test Coverage
Happy paths:
- Workflow JSON extracted from EXIF Exif item (LE)
- Prompt JSON extracted
- Big-endian (MM) EXIF parsing
- Both prompt and workflow present in separate EXIF entries
Negative paths (each yields `{}` without throwing):
- AVIF major brand is not "avif"
- Meta box missing
- iinf has no Exif item
- EXIF entry uses an unrecognized key
- EXIF entry has malformed JSON
- infe version is unsupported (1)
- iloc box missing while iinf has Exif
- Buffer too short for valid header
