Root cause: scanExistingStreamers only read channel.members, which is
EMPTY after a gateway restart because the selfbot's guild member cache
hasn't been populated yet. So any user who was ALREADY on camera /
screen-sharing when the bot (re)joined was never detected → no video.
Fix: when the member cache is empty, fall back to guild.members.fetch()
(REST GET /guilds/{id}/members — user-token compatible; the bot-only
GET /channels/{id}/voice-states returns 404 for selfbots, verified live)
which populates member.voice states, then re-scan channel.members for
streaming/selfVideo.
- scanExistingStreamers is now async; trackChannel fire-and-forgets it
- logs source=cache vs source=rest-members for observability
- +1 test: cold-start channel.members empty → REST fetch → watch camera user
- 191/191 tests pass, typecheck + build + biome clean
