## Summary by cubic
Adds a new edit_file tool that uses the Dyad Turbo File Edit API to
apply targeted edits to existing files and write the result. Also
disables the search_replace tool and simplifies error output to only
show the message.

- **Dependencies**
- Requires Dyad Pro API key in settings (providerSettings.auto.apiKey).
- DYAD_ENGINE_URL env var can override the default
https://engine.dyad.sh/v1.
