Four small follow-ups from the 0.9.0 audit, none of them
user-visible:
- Migration 0007 drops `chapters_manga_idx`. The 0001 schema declared
both `UNIQUE (manga_id, number)` and `CREATE INDEX chapters_manga_idx
ON (manga_id, number)`, but Postgres maintains an identical index
for the unique constraint automatically — the explicit one was just
paying for a second per-write update. Query plans are unchanged
because the planner already preferred the constraint's index.
- `upload::parse_image` sniffs from the first 64 bytes instead of the
full image buffer. `infer` only looks at magic bytes anyway, so
scanning 20 MiB is wasted work. Functionally identical; cheaper in
the hot path.
- AVIF was on the whitelist but had no test fixture. New `avif_bytes`
helper produces a minimal `ftyp avif` header that `infer` recognises,
and a new `accepts_avif` unit test covers the path end-to-end.
- Frontend `request()` sets `credentials: 'include'`. Same-origin
callers see no change (default was already `'same-origin'`), but the
first user who configures `CORS_ALLOWED_ORIGINS` for a cross-origin
deployment gets working cookies without having to chase a runtime
ApiError trail.
No version bump.
