Major changes: - Consolidated schema into single migration with IRC envelope format - Messages table stores command/from/to/body(JSON)/meta(JSON) per spec - Per-client delivery queues (client_queues table) with fan-out - In-memory broker for long-poll notifications (no busy polling) - GET /messages supports ?after=<queue_id>&timeout=15 long-polling - All commands (JOIN/PART/NICK/TOPIC/QUIT/PING) broadcast events - Channels are ephemeral (deleted when last member leaves) - PRIVMSG to nicks (DMs) fan out to both sender and recipient - SPA rewritten in vanilla JS (no build step needed): - Long-poll via recursive fetch (not setInterval) - IRC envelope parsing with system message display - /nick, /join, /part, /msg, /quit commands - Unread indicators on inactive tabs - DM tabs from user list clicks - Removed unused models package (was for UUID-based schema) - Removed conflicting UUID-based db methods - Increased HTTP write timeout to 60s for long-poll support
