Replace the user-token selfbot voice path with an official Discord bot using
discord.js 14 + @discordjs/voice 0.19. The bot logs in with the stored testbot
token, joins the target voice channel, passes the DAVE/MLS E2EE handshake, and
receives per-user Opus audio via VoiceReceiver (the STT input path). ToS-safe.
Live-verified: bot joined guild "사지방" / channel "일반" and reached Ready.
Selfbot (gate.mjs/join.mjs) kept only for the deferred screenshare-video track,
which official bots cannot receive. Docs updated (README/PLAN); M1 done on bot path.
