Adds a BlacklistEntry model (type WORD|LINK|HASHTAG, unique per
type+value) with a new admin module at /p/[secret]/blacklist —
add/list/delete entries, filterable by type.
Enforcement, per explicit spec from this session:
- New posts are checked at creation time (posts.create) against the
current blacklist (whole-word regex match for WORD, domain match
incl. subdomains for LINK, exact match for HASHTAG) and auto-hidden
immediately via the existing hiddenAt mechanism if matched — never
blocks creation, just hides right after, reversible via
admin.unhidePost. Logged as HIDE_POST with moderatorId "SYSTEM".
- Adding a new entry retroactively scans existing non-hidden posts
(capped at 5000 for safety) and hides matches too, logged per-post
under the admin who added the entry.
- Removing an entry does NOT auto-unhide already-hidden posts —
that stays a manual review step via the existing hide/unhide UI.
Matching lives in src/lib/blacklist.ts: word matching uses \b word
boundaries (a blacklisted "ass" won't match "assist"), link matching
extracts URLs and compares hostnames including subdomains.
Scope: post captions/hashtags only, not comment bodies — comments
don't have a hiddenAt field yet, so this is a natural follow-up once
they do, using the same pattern.
