kickside/slack

Slack connection provider for Kickside.

It owns:

• a kickside.connection:connection binding for bot-token health checks and resource discovery
• a kickside.connection:reply_provider binding for sending messages back to Slack channels
• a normalized inbound adapter for Slack message events that calls kickside.dm:receive (DMs) and kickside.channel:receive (channels)

Inbound Slack messages arrive over Socket Mode, not ordinary webhooks. The socket process opens a connection per Slack bot (via apps.connections.open with the app-level token), receives Events API envelopes, acknowledges each, and passes the connection component id and event into the inbound adapter as the system socket process; DM resolves the sender from the link and handles thread ownership, idempotency, and session routing.
