Cameron CordesandClaude Opus 5.5	b95adb4f77	fix(images): pick the decoder from the bytes, not the extension `image::open` chooses the decoder by extension, so a PNG saved as .jpg (Android screenshots, chat exports) failed thumbnails, previews, perceptual hashes, insights and face crops with "Illegal start bytes: 8950". New `file_types::open_image` sniffs the header and falls back to the extension when it's unknown; every decode site uses it.

fix(images): pick the decoder from the bytes, not the extension

`image::open` chooses the decoder by extension, so a PNG saved as .jpg
(Android screenshots, chat exports) failed thumbnails, previews,
perceptual hashes, insights and face crops with "Illegal start bytes:
8950". New `file_types::open_image` sniffs the header and falls back to
the extension when it's unknown; every decode site uses it.
