First public release of dsh-autonomy.
- Adds an always-visible Chat | Agent switch above the DeepSeek Harness Web composer.
- Keeps the current session, model, preset, sandbox, history, and draft intact while switching.
- Chat mode removes model tool schemas and guards tool execution; Agent restores normal DSH behavior.
- Persists the selected mode through reloads and full DSH restarts.
Tested with DeepSeek Harness 0.1.0-rc.6.
