/**
 * Fires when a new message arrives in a monitored Slack channel.
 *
 * This trigger listens for the "message.created" event and starts the
 * triage workflow for each incoming message. The workflow then classifies
 * the request and routes it to the appropriate person/channel.
 *
 * Customize:
 *   - Add filters to ignore bot messages or specific channels
 *   - Switch to "slack:reactionAdded" to triage only when someone reacts with a specific emoji
 *   - Add "slack:memberJoinedChannel" to welcome new members
