- When room_id == 1, server/main automatically patch blivedm to connect
to fake_room.py on 127.0.0.1:8081 (bot web UI port + 1)
- Any other room id restores real Bilibili (unpatch)
- fake_room.py (gitignored, not packaged): headless fake live room with
bilibili-compatible init APIs (/x/web-interface/nav, /room/v1/Room/get_info,
/xlive/web-room/v1/index/getDanmuInfo) and WS /sub protocol (AUTH/HEARTBEAT/
SEND_MSG_REPLY), plus stdin/HTTP /emit control for danmaku/gift/blind box/
guard/super chat/enter/follow
- Verified end-to-end: all events flow through blivedm and render rules
(gift -> 感谢由Baka投喂的小电视, blind box, guard, super chat, custom
danmaku template, enter room)
