Show editor availability (vibe-kanban) (#1325)

* Perfect! I've successfully refactored the editor opening code to use the `CommandBuilder` pattern. Here's a summary of the changes:

- Added `use executors::command::CommandBuilder;`

- Changed return type from `Vec<String>` to `CommandBuilder`
- Now returns a proper `CommandBuilder` that handles shell word splitting correctly
- Supports quoted strings in custom commands (via `shlex` on Unix, `winsplit` on Windows)

- Uses `CommandBuilder` pattern: `build_initial()` → `into_resolved()`
- Resolves executables properly on **both Unix and Windows** (previously only Windows had resolution)
- Better error messages that show which executable couldn't be found
- Maps `ExecutorError` to `io::Error` for consistency with the function signature

✅ **Consistent cross-platform behavior**: Unix now also resolves executables properly
✅ **Sophisticated PATH resolution**: Uses login shell refresh logic for finding executables
✅ **Proper shell word splitting**: Handles quoted strings correctly in custom commands
✅ **Better error messages**: Shows exactly which executable couldn't be found
✅ **Follows established patterns**: Uses the same proven pattern as other executors in the codebase

All checks pass: compilation, tests, and Clippy linting. The code is ready!

Perfect! All changes have been successfully implemented and tested. Here's what was done:

- Changed from: `Result<ResponseJson<ApiResponse<OpenEditorResponse>>, StatusCode>`
- Changed to: `Result<ResponseJson<ApiResponse<OpenEditorResponse>>, ApiError>`

- Changed from: `Err(StatusCode::INTERNAL_SERVER_ERROR)` (generic 500 error)
- Changed to: `Err(ApiError::Io(e))` (passes actual error message)

Now when the editor command fails (e.g., executable not found), the API will return a proper error response with the actual error message like:
- `"IoError: Editor command not found: Executable 'cursor' not found in PATH"`

This matches the pattern already used in `task_attempts.rs` and provides meaningful feedback to the frontend, which can display the error to users or fall back to the editor selection dialog.

All checks pass: compilation, TypeScript type checking, and Clippy linting!

Perfect! All changes have been successfully implemented and tested. Here's a summary:

- New `EditorOpenError` enum with `ExecutableNotFound` variant
- Contains structured fields: `executable` (the command that wasn't found) and `editor_type` (the configured editor)
- Exports to TypeScript with discriminated union type

- Changed `open_file()` return type: `Result<Option<String>, io::Error>` → `Result<Option<String>, EditorOpenError>`
- Changed `spawn_local()` return type: `io::Result<()>` → `Result<(), EditorOpenError>`
- Maps `ExecutorError::ExecutableNotFound` to structured `EditorOpenError::ExecutableNotFound`
- Removed unused `io` import

- Added `EditorOpen(#[from] EditorOpenError)` variant
- Maps to `StatusCode::BAD_REQUEST` (400) instead of 500
- Returns proper error type: `"EditorOpenError"`

- **`crates/server/src/routes/projects.rs:452`**: Changed from `ApiError::Io(e)` to `ApiError::EditorOpen(e)`
- **`crates/server/src/routes/task_attempts.rs:965`**: Changed from generic `TaskAttemptError::ValidationError` to `ApiError::EditorOpen(e)`

```typescript
export type EditorOpenError = {
  "type": "executable_not_found",
  executable: string,
  editor_type: string,
};
```

Now when an editor executable isn't found, the frontend receives:
```json
{
  "type": "executable_not_found",
  "executable": "cursor",
  "editor_type": "CURSOR"
}
```

Instead of a generic 500 error. This allows the frontend to:
- Show specific error messages ("Cursor not found in PATH")
- Suggest alternative editors
- Provide installation links or PATH setup instructions
- Offer to open the editor settings dialog

All checks pass: compilation, TypeScript type checking, Clippy linting, and tests!

* Refactor editor config (vibe-kanban a60c079b)

Currently edit config is defined in crates/services/src/services/config/versions/v2.rs, we should consider moving it into a module instead.
Weigh pros and cons, best practices and the current architecture

* Review editor refactor (vibe-kanban 829ba3e5)

Review the last 5 commits

There's a rebase conflict in `GeneralSettings.tsx` that needs resolution. The conflict is in the imports:

**Conflict (lines 41-49):**
- **Your branch (HEAD)**: Imports from `ThemeProvider` and `ConfigProvider` (PascalCase)
- **Main branch**: Imports from `theme-provider` and `config-provider` (kebab-case) + adds new editor availability features

**Resolution needed:**
Keep the main branch version because it:
1. Uses the newer kebab-case file naming convention
2. Adds `useEditorAvailability` and `EditorAvailabilityIndicator` features that complement your error handling work

The resolved imports should be:
```typescript
import { useEditorAvailability } from '@/hooks/useEditorAvailability';
import { EditorAvailabilityIndicator } from '@/components/EditorAvailabilityIndicator';
import { useTheme } from '@/components/theme-provider';
import { useUserSystem } from '@/components/config-provider';
```

Would you like me to resolve this conflict and continue the rebase?

Show available editors at startup (vibe-kanban 9f1ea85f)

When onboarding, show a green checkmark next to installed editors. Use the editor struct refactored in the last 6 commits to make it work. Check eveyer editor in the enum at vk startup. Mkae sure editors being unailable does NOT break anything

Fix imports after rebase - use PascalCase for ThemeProvider and ConfigProvider

Perfect! All changes complete. Let me create a summary:

✅ **Changes made:**

- Added `CheckEditorAvailabilityQuery::decl()`
- Added `CheckEditorAvailabilityResponse::decl()`

New types exported:
```typescript
export type CheckEditorAvailabilityQuery = { editor_type: EditorType };
export type CheckEditorAvailabilityResponse = { available: boolean };
```

- Added import for `CheckEditorAvailabilityResponse`
- Updated `checkEditorAvailability` method:
  - Parameter type: `string` → `EditorType` (type-safe enum)
  - Return type: `{ available: boolean }` → `CheckEditorAvailabilityResponse`

- ✅ Full type safety for editor availability checking
- ✅ Frontend uses typed `EditorType` enum instead of strings
- ✅ Consistent with other query/response type patterns
- ✅ All checks pass (TypeScript + Rust compilation)

The editor availability feature now has complete type safety from backend to frontend!

* Fix i18n (vibe-kanban 57188642)

For new editory avilability added in the last 3 commits.
Run @scripts/check-i18n.sh until it passes. Make sure to check the script and set GITHUB_BASE_REF to main

* Fix import: use github not github_service after rebase
