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

b8dcaa2aa1 Fix paywall false positives + add og:image fallbacks
- Body extractor falls back to <article>/<main> container text when
  <p> extraction is sparse, catching <br>-separated bodies (Phoronix).
- Detect Cloudflare bot-block / JS-challenge pages on 403/503 and
  treat them as transport failures rather than paywalls (Brooklyn Vegan).
- og:image extractor falls back to img.wp-post-image and the first
  content <img> in <article>/<main>, with lazy-load placeholder
  handling via data-src / data-lazy-src (Hardcore Gaming 101).
- New -backfill-paywall flag re-checks paywalled=1 rows with the
  current logic, clearing false positives and filling missing thumbs.

509a0fc7a7 Harden paywall detection + render paywalled stamp on cards
Bypass-UA retry (Googlebot + Google referer) for soft paywalls, JSON-LD
gating scoped to Article-typed nodes, HTTP 402 treated as explicit
paywall, Wayback freshness filter (30d cap), archive.today as secondary
archive fallback, and transport failures no longer trigger snapshot
swaps. When gating is detected and no archive workaround succeeds, the
story is stored with paywalled=1 and the web card renders a diagonal
red rubber-stamp overlay so readers know the link is gated.

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

3537e073e9 !explain via reaction: thread-reply with a 3-bullet TL;DR
When a user reacts  on one of Pete's posts, fetch the article body,
ask Ollama for a 3-bullet summary, and post it as a threaded reply
rooted at the original story event. Per-process cooldown of 5min per
story keeps repeated reactions from re-summarizing.

- ingestion.FetchArticleBody: visible <p> text capped at 8000 chars
- classifier.OllamaClient.GenerateText: non-JSON variant
- storage.GetStoryByGUID: full row lookup
- matrix.PostThreadedReply: m.thread + m.in_reply_to fallback
- poster.SetReactionCallback: optional hook fired after recording
- New package: internal/explainer

e26b69e43f Paywall detection: swap to Wayback snapshot when article body is gated
Fetch each new article once and measure visible <p> text. If body is below
500 chars (or fetch fails), resolve a Wayback snapshot via the
archive.org/wayback/available API and use that URL for both the og:image
fallback and the posted link. Dedup keys stay derived from the original
URL so paywalled/non-paywalled hits collide as before.

- New: internal/ingestion/article.go (FetchArticleMeta via goquery)
- New: internal/ingestion/wayback.go (ResolveWayback)
- Removed: internal/ingestion/og.go (folded into article.go)
- poller.go: dedup first, then one article fetch, then snapshot fallback
