Cyberspace API 0.5.1

• Auth
  • POST /v1/auth/register is temporarily disabled — regular users don't have API access for now, so public signup is turned off. The route returns 404 until re-enabled.
• Replies
  • Posting a reply now auto-watches the thread server-side, honoring the autoWatchOnReply setting (default on; set false to opt out). Watching a thread drives thread_reply notifications.
• Thread watching
  • New endpoints to watch threads manually: GET /v1/posts/:id/watch (status), POST /v1/posts/:id/watch (watch, idempotent), DELETE /v1/posts/:id/watch (unwatch), and GET /v1/watches (list watched threads, paginated, newest first).
  • Subscriptions now use a deterministic ID per user+thread, so reply/mention/manual watches dedup to a single entry and unwatch clears all of them.
