feat: direct messages

1:1 conversations (userAId < userBId dedup pair), messages,
per-participant read tracking (conversation_reads). Block relationship
is enforced on every send. UI: /messages list + /messages/[id] thread
(5s poll), MessageButton on profiles, unread-badged nav icon.

This completes the social-feature backlog: notifications, rate
limiting, blocking, reporting, search/discovery, mentions, DMs, plus
fixes for the recipe-visibility 404, follow race, and 2-level comment
thread cap found during the earlier audit.
