/**
 * `conversation_inference_profile_updated` SSE event.
 *
 * Broadcast to clients when a conversation's inference-profile override
 * changes. `profile` is the profile name (a key in `llm.profiles`) or
 * `null` when the override is cleared and the conversation falls back to
 * the workspace `llm.activeProfile` resolution.
 *
 * Canonical wire-contract source. Daemon code imports the type
 * directly from this file; external consumers import via
 * `@vellumai/assistant-api`.
