/**
 * `conversation_list_invalidated` SSE event.
 *
 * Tells clients their sidebar conversation list is stale and should be
 * refetched. `reason` categorizes the underlying cause so clients can
 * pick narrower refresh strategies if they choose.
 *
 * Global event (no `conversationId`): the conversation list is per-user,
 * not per-conversation, and the daemon fans this out across every active
 * client of the user.
 *
 * Canonical wire-contract source. Daemon code imports the type directly
 * from this file; external consumers import via `@vellumai/assistant-api`.
