v2 phase 4+5: Discord via Chat SDK, expanded MCP tools, message seq IDs
- Chat SDK bridge + Discord adapter (gateway listener, message routing) - MCP tools refactored into modular structure: core (send_message, send_file, edit_message, add_reaction), scheduling (schedule/list/cancel/pause/resume tasks), interactive (ask_user_question, send_card), agents (send_to_agent) - Message seq IDs: shared integer sequence across messages_in/out so agents see small numeric IDs instead of platform snowflakes - busy_timeout=5000 for session DB (poll loop + MCP server concurrent access) - Always copy agent-runner source to fix stale cache when non-index files change - Seed script for Discord testing, e2e test script Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
