Root cause of "not anonymous":
1. Confess deleted via raw SQL with no MESSAGE_DELETE broadcast
2. Frontend extractIds only accepted message_id, but deletes send id
so live clients never removed deleted messages without refresh
Fix:
- Intercept /confess at message create: never store or broadcast the
original; post only the anonymous bot message
- Accept both id and message_id on MESSAGE_DELETE in the WS store
- Include both fields on delete broadcasts
Root cause: makeSender requires bot_servers membership, but create
flow never auto-added bots when users only picked a channel.
- Start() resolves config.channel_id → server and upserts bot_servers
- Confess cursor uses (created_at,id) so deletes don't stall polling
- Added @Summary/@Router/@Param/@Success/@Security annotations to all API handlers
- Regenerated docs/swagger.json, docs/swagger.yaml, docs/docs.go with full endpoint definitions
- Fixed generated docs.go to remove unsupported LeftDelim/RightDelim fields
