Rewrite the wiki as full engineering documentation Replaces the default stub with 16 pages covering architecture, the agent debate, the execution guard, the data model, the real-time layer, the API, the MCP tool server, the Telegram bot, configuration, operations, quality and testing, engineering decisions, an incident log and the roadmap. Adds a custom _Sidebar for navigation between all of them. INC-003 documents the WebSocket flap with a reproduced root cause: redis-py 8.1.0's implicit DEFAULT_SOCKET_TIMEOUT of 5s is identical to channels_redis's brpop_timeout of 5s, so the read deadline races the blocking window. Measured 4/4 failures at the old value and 4/4 clean at the shipped value.
