## Problem
`dispatchTask()` shells out to `openclaw gateway call sessions.patch` which
times out when the gateway is busy, causing:
1. Notifications never fire (they're at the end of dispatchTask)
2. Worker state may not be recorded
3. Workers run silently
## Solution (3 changes)
### 1. Make `ensureSession` fire-and-forget
Session key is deterministic, so we don't need to wait for confirmation.
Health check catches orphaned state later.
### 2. Use runtime API for notifications instead of CLI
Pass `runtime` through opts and use direct API calls:
- `runtime.channel.telegram.sendMessageTelegram()`
- `runtime.channel.whatsapp.sendMessageWhatsApp()`
- etc.
### 3. Move notification before session dispatch
Fire workerStart/workerComplete notifications early (after label transition)
before the session calls that can timeout.
## Files Changed
- lib/dispatch.ts — fire-and-forget ensureSession, early notification, accept runtime
- lib/notify.ts — use runtime API for direct channel sends
- lib/services/pipeline.ts — early notification, accept runtime
- lib/services/tick.ts — pass runtime through to dispatchTask
- lib/tool-helpers.ts — accept runtime in tickAndNotify
- lib/tools/work-start.ts — pass api.runtime to dispatchTask
- lib/tools/work-finish.ts — pass api.runtime to executeCompletion/tickAndNotify
