Replaces the Redis-over-Tailscale handoff with a far simpler HTTP surface
on the existing public API — no Redis client, Tailscale, or firewall changes
needed on the dev side.
- GET /ai/stream — SSE feed of every ingested message, reads the internal
Redis stream; resumes from Last-Event-ID on reconnect (no missed messages);
heartbeats keep the connection warm through proxies
- POST /ai/drafts — writeback: creates a ContentDraft (PENDING_REVIEW) that
shows up in the admin /admin/drafts review UI
- AiStreamGuard — static bearer token auth (AI_STREAM_TOKEN), accepts header
or ?token= query for browser EventSource
- Remove Tailscale sidecar + public Redis port; Redis stays internal-only
