Supports: MOS

Conversion re-encodes pixels: EXIF metadata and color profiles are not carried over, EXIF rotation is applied, and animated GIF, WebP, and AVIF inputs keep only their first frame (flagged on the result). Inputs are validated by their actual bytes, and every output is signature-checked before it counts as done.

These knobs map straight onto the vendored encoder. The row meta names the encoder that actually ran, plus the size delta.
