Adds a Discord channel using the discord.py Gateway client, mirroring the Telegram adapter's shape: text/media send and receive, typing, edit, reactions, and exposure/allowlist gating. Outbound text over Discord's 2000-character limit is split into multiple messages sent in order.

… 3.12 discord.py's voice-playback module unconditionally imports the deprecated stdlib audioop module even though talon never uses Discord voice features, which fails CI under this package's warnings-as-errors pytest config.

readme: acknowledged
Discord's Gateway redelivers the bot's own outbound messages through on_message; the from_self metadata flag was treated as an admitted sender (a case meant for Telegram/WhatsApp operator-device messages), so every reply looped back into a new agent invocation. Drop self-authored messages before exposure checks in every mode. Also fix a startup race in the gateway connect wait: on the normal success path the readiness task wins FIRST_COMPLETED, leaving the actual gateway task in `pending` -- which then got cancelled right after marking the adapter connected, killing the receive loop.
