## Summary
- Added `sendTelemetryException()` utility that sends `$exception`
events to PostHog via the main→renderer telemetry bridge, including
error type, message, and stack trace
- Wired error capture into all three IPC handler factories
(`createTypedHandler`, `createLoggedTypedHandler`,
`createLoggedHandler`) so every `ipcMain.handle` error is automatically
reported with the IPC channel name as context
- Errors are still re-thrown after capture so existing behavior is
unchanged

## Test plan
- All 844 existing tests pass
- Verify in dev that IPC handler errors appear as `$exception` events in
PostHog with `ipc_channel` property
- Confirm telemetry opt-out still prevents exception events from being
sent (via existing `before_send` filter)
