Cameron CordesandClaude Opus 5.5 6135034d09 feat(versions): e2e fixtures, check_versions, docs 
Fixtures gain an XMP-linked version (renamed file), a name-linked version
and an edit with a reference photo; e2e.sh counts with include_versions and
runs check_versions.py. CLAUDE.md documents the feature.

"""Generate the synthetic e2e media library.
Every image is rendered with its own relative path, date and scenario
burned into the pixels, so an agent looking at a screenshot can tell
exactly which fixture is on screen. EXIF (dates, GPS, camera) is stamped
in a single exiftool batch. A `manifest.json` next to the media records
what was generated and what the server should derive from it, so tests
can assert against it instead of hardcoding counts.
Runs on native Linux with ffmpeg / exiftool, or in WSL driving the Windows
binaries (ffmpeg.exe / exiftool.exe), in which case every path handed to
them goes through `wslpath -w`.
Usage: gen_fixtures.py <out_dir> [--import DIR]
<out_dir>/media/ the pristine library (never served directly)
<out_dir>/manifest.json what's in it
