AI Summary

Adds per-phase timing logs in debug mode to help developers break down non-AI execution time in CI logs, covering connection, initializers, steps, and device calls.

Key Highlights

  • Debug logs show timing for each phase of a run
  • Breaks down non-AI time in CI logs

New Features

  • Per-phase timing logging
  • Debug timing for steps, initializers, and device calls

Full Release Notes

With `--log-level=debug`, each phase of a run now prints how long it took, so non-AI time can be broken down from a CI log.

## Per-Phase Timings in Debug Logs (#451)

```
D: [timing] agent.initializers 15879ms
D: [timing] step.screenshot 105ms
D: [timing] step.executeAction 2470ms
D: [timing] device.waitForAppToSettle 5849ms
```

Covers connection, initializers, steps and their phases, and device calls. Default output does not change.
