v0.4.0: Discord + Slack gateways

Adds Discord gateway: REST API POST /channels/{id}/messages for
sending, HTTP GET for polling messages. Maps Discord mentions to
:user-input signals. HITL commands intercepted before injection.

Adds Slack gateway: Web API chat.postMessage for sending,
conversations.history for polling. Uses SLACK_TOKEN from vault.
Each gateway registered in *gateway-registry* following the same
jail-loaded skill pattern as Telegram and Signal.

Registry now has 4 platforms: telegram, signal, discord, slack.
