fc4cab3ad6 Seek 5s into videos for thumbnail extraction
The 0.5s seek often landed on the initial keyframe or a fade-in,
producing blocky thumbnails. Aim ~5s in instead, with an ffprobe
midpoint fallback for clips shorter than that and a 2s → 0
retry chain if the seek still overshoots.

04a3c41bed Fall back to ffmpeg when Go's JPEG decoder rejects a source
Go's stdlib image/jpeg refuses some valid-but-rare features such as
4:1:1 luma/chroma subsampling (ANN's CDN serves these). When the
in-process decode fails, route the bytes through ffmpeg the same way
we already do for video sources.

70e1dfc2b8 Extract frame for video thumbnails via ffmpeg
mp4/webm/mov/m4v/mkv URLs now route to a frame-extraction path with a
larger 64 MiB download cap, and ffmpeg pulls a single resized frame
that the existing avifenc step turns into the cached thumb. ffmpeg is
optional: if missing, we fall through like any other build failure
and the handler redirects to the source URL.

9e5ba5aafc Fix SSRF, XSS, dedup, force-post, and DB hot-path issues
- Add internal/safehttp: hardened HTTP client (DNS-resolved dial guard
  blocking loopback/RFC1918/CGNAT/link-local, redirect re-validation,
  body-size cap) and rewire article/feed/thumb clients through it
- Cap goquery body at 5 MiB so a hostile origin can't OOM the process
- search.js: reject non-http(s) hrefs to block stored XSS via javascript:
- dedup: tracking-param key "CMP" was unreachable (lookup lowercases);
  fixed to "cmp" so CMP= is actually stripped from canonical URLs
- ForcePost: postItem now returns bool; on dedup-skip ForcePost returns
  false so !post falls back to DB lookup instead of silently consuming
- Bound reaction callbacks behind an 8-slot semaphore; drop overflow
- Add stories indexes on (channel, classified, seen_at DESC),
  (classified, seen_at DESC), and partial image_url to kill full scans
  in IsKnownImageURL and ORDER BY seen_at hot paths
- Surface FTS5 probe Scan error instead of swallowing it

9bc8743b5e Handle AVIF source images in thumb pipeline
Decode AVIF via avifdec when Go's image.Decode can't, and pass-through
small AVIFs (<=800px wide) by caching the original bytes instead of
re-encoding.

5ea64c1d32 Paywall signal detection, sqlite driver registration, /img route fix
- Detect explicit paywall markers (article:content_tier meta, JSON-LD
  isAccessibleForFree) so metered articles fall back to Wayback even
  when body length is above threshold
- Blank-import go.mau.fi/util/dbutil/litestream so the sqlite3-fk-wal
  driver mautrix's cryptohelper depends on is registered
- Fix /img route: Go ServeMux requires {wildcard} to be a whole segment,
  so capture {name} and strip the .avif suffix in the handler

bddd15f7d1 Web UI: music channel, posted-to-Matrix glow, redesigned index, AVIF thumbnails
- Add music as a fourth channel (nav + theme color)
- Glowing themed border on cards that have been posted to Matrix
- Replace per-channel index sections with: "Pete just posted" strip,
  channel dashboard (last post, 24h count, totals), unified latest feed
- /img proxy: SSRF-guarded thumbnail re-encoder that resizes to 800px
  and runs avifenc -q 45, cached under data/img-cache
