Adds a helper that forces selected tools to launch in a new window
instead of reusing the current one. This is applied to code editors,
diff/merge, and terminal launches, aligning behavior across platforms.
Presets and defaults are updated to pass new-window or equivalent flags,
and tests verify the new behavior for common tools.
- Update code editors to always use a new window when opened
- Normalize launch flags for Windows terminals and diff tools
- Add tests covering new-window behavior for common tools
Adds a new external tools subsystem to detect and launch
diff and editor tools across Windows, macOS, and Linux.
It exposes data models for tools, commands, and results to the UI
and serializes them for consumption by the app.
- Implement cross-platform discovery of editors and diff tools
- Expose serialized results to the UI for user selection
- Centralize per-OS known tool lists and overrides
