- `createHeartbeatLoop()` convenience helper that returns a bound `CompanionHeartbeatLoop`
- optional `defaultSessionId` for canvas helper calls so `sessionId` can be omitted per call
- `dispose()` lifecycle helper for unified runtime teardown
- stream passthrough helpers (`subscribeAgentStream()`, `waitForAgentStream()`)
- stream passthrough helpers (`subscribeAgentStream/Typing/ContextWarning`, `waitForAgentStream/Typing/ContextWarning`)
- `src/companion/heartbeatLoop.ts` provides `CompanionHeartbeatLoop` for periodic heartbeat scheduling (`publishHeartbeat`) with start/stop safety, optional interval jitter (`jitterRatio`) to spread load, `tickNow()` for manual sends, success/error hooks, failure observability (`failureCount`, `lastFailure`, `getState()`), and optional auto-stop after repeated failures.
