upload() ran fitStill (ffmpeg scale+pad) on every image except hero,
including the start/handoff still. Four chained extends resampled the
anchor frame four times and destroyed identity even with the hero
reference and lock text intact.
- upload(): only fit when the still's aspect truly differs from the
job canvas (needsFit); never fit hero or start regardless.
- Track handoffSource (anchor|extract) and whether the start frame was
fitted; surface both in job metadata and Details.
- extendSelected(): re-binding an already-selected clip on task switch
must not stomp the user's overridden locks/settings back to the
clip's saved values (regression introduced by the last hotfix push).
- Add tests/studio2-extend-fit.test.mjs: two extends at identical
width/height reach Comfy with the anchor PNG byte-identical, no
ffmpeg fit.
