* refactor(wizard): rebuild project creation flow as modular TypeScript components

Replace the monolithic `ProjectCreationWizard.jsx` with a feature-based TS
implementation under `src/components/project-creation-wizard`, while preserving
existing behavior and improving readability, maintainability, and state isolation.

Why:
- The previous wizard mixed API logic, flow state, folder browsing, and UI in one file.
- Refactoring and testing were difficult due to tightly coupled concerns.
- We needed stronger type safety and localized component state.

What changed:
- Deleted:
  - `src/components/ProjectCreationWizard.jsx`
- Added new modular structure:
  - `src/components/project-creation-wizard/index.ts`
  - `src/components/project-creation-wizard/ProjectCreationWizard.tsx`
  - `src/components/project-creation-wizard/types.ts`
  - `src/components/project-creation-wizard/data/workspaceApi.ts`
  - `src/components/project-creation-wizard/hooks/useGithubTokens.ts`
  - `src/components/project-creation-wizard/utils/pathUtils.ts`
  - `src/components/project-creation-wizard/components/*`
    - `WizardProgress`, `WizardFooter`, `ErrorBanner`
    - `StepTypeSelection`, `StepConfiguration`, `StepReview`
    - `WorkspacePathField`, `GithubAuthenticationCard`, `FolderBrowserModal`
- Updated import usage:
  - `src/components/sidebar/view/subcomponents/SidebarModals.tsx`
    now imports from `../../../project-creation-wizard`.

Implementation details:
- Migrated wizard logic to TypeScript using `type` aliases only.
- Kept component prop types colocated in each component file.
- Split responsibilities by feature:
  - container/orchestration in `ProjectCreationWizard.tsx`
  - API/SSE and request parsing in `data/workspaceApi.ts`
  - GitHub token loading/caching behavior in `useGithubTokens`
  - path/URL helpers in `utils/pathUtils.ts`
- Localized UI-only state to child components:
  - folder browser modal state (current path, hidden folders, create-folder input)
  - path suggestion dropdown state with debounced lookup
- Preserved existing UX flows:
  - step navigation and validation
  - existing/new workspace modes
  - optional GitHub clone + auth modes
  - clone progress via SSE
  - folder browsing + folder creation
- Added focused comments for non-obvious logic (debounce, SSE auth constraint, path edge cases).

* refactor(quick-settings): migrate panel to typed feature-based modules

Refactor QuickSettingsPanel from a single JSX component into a modular TypeScript feature structure while preserving behavior and translations.

Highlights:
- Replace legacy src/components/QuickSettingsPanel.jsx with a typed entrypoint (src/components/QuickSettingsPanel.tsx).
- Introduce src/components/quick-settings-panel/ with clear separation of concerns:
  - view/: panel shell, header, handle, section wrappers, toggle rows, and content sections.
  - hooks/: drag interactions and whisper mode persistence.
  - constants.ts and types.ts for shared config and strict local typing.
- Move drag logic into useQuickSettingsDrag with explicit touch/mouse handling, drag threshold detection, click suppression after drag, position clamping, and localStorage persistence.
- Keep user-visible behavior intact:
  - same open/close panel interactions.
  - same mobile/desktop drag behavior and persisted handle position.
  - same quick preference toggles and wiring to useUiPreferences.
  - same hidden whisper section behavior and localStorage/event updates.
- Improve readability and maintainability by extracting repetitive setting rows and section scaffolding into reusable components.
- Add focused comments around non-obvious behavior (drag click suppression, touch scroll lock, hidden whisper section intent).
- Keep files small and reviewable (all new/changed files are under 300 lines).

Validation:
- npm run typecheck
- npm run build

* refactor(quick-settings-panel): restructure QuickSettingsPanel import and create index file

* refactor(shared): move shared ui components to share/view/ui without subfolders

* refactor(LanguageSelector): move LanguageSelector to shared UI components

* refactor(prd-editor): modularize PRD editor with typed feature modules

Break the legacy PRDEditor.jsx monolith into a feature-based TypeScript architecture under src/components/prd-editor while keeping behavior parity and readability.

Key changes:

- Replace PRDEditor.jsx with a typed orchestrator component and a compatibility export bridge at src/components/PRDEditor.tsx.

- Split responsibilities into dedicated hooks: document loading/init, existing PRD registry fetching, save workflow with overwrite detection, and keyboard shortcuts.

- Split UI into focused view components: header, editor/preview body, footer stats, loading state, generate-tasks modal, and overwrite-confirm modal.

- Move filename concerns into utility helpers (sanitize, extension handling, default naming) and centralize template/constants.

- Keep component-local state close to the UI that owns it (workspace controls/modal toggles), while shared workflow state remains in the feature container.

- Reuse the existing MarkdownPreview component for safer markdown rendering instead of ad-hoc HTML conversion.

- Update TaskMasterPanel integration to consume typed PRDEditor directly (remove any-cast) and pass isExisting metadata for correct overwrite behavior.

- Keep all new/changed files below 300 lines and add targeted comments where behavior needs clarification.

Validation:

- npm run typecheck

- npm run build

* refactor(TaskMasterPanel): update PRDEditor import path to match new structure

* refactor(TaskMaster): Remove unused TaskMasterSetupWizard and TaskMasterStatus components

* refactor(TaskDetail): remove unused TaskIndicator import

* refactor(task-master): migrate tasks to a typed feature module

- introduce a new feature-oriented TaskMaster domain under src/components/task-master

- add typed TaskMaster context/provider with explicit project, task, MCP, and loading state handling

- split task UI into focused components (panel, board, toolbar, content, card, detail modal, setup/help modals, banner)

- move task board filtering/sorting/kanban derivation into dedicated hooks and utilities

- relocate CreateTaskModal into the feature module and keep task views modular/readable

- remove legacy monolithic TaskList/TaskDetail/TaskCard files and route main task panel to the new feature panel

- replace contexts/TaskMasterContext.jsx with a typed contexts/TaskMasterContext.ts re-export to the feature context

- update MainContent project sync logic to compare by project name to avoid state churn

- validation: npm run typecheck, npm run build

* refactor(MobileNav): remove unused React import and TaskMasterContext

* refactor(auth): migrate login and setup flows to typed feature module

- Introduce a new feature-based auth module under src/components/auth with clear separation of concerns:\n  - context/AuthContext.tsx for session lifecycle, onboarding status checks, token persistence, and auth actions\n  - view/* components for loading, route guarding, form layout, input fields, and error display\n  - shared auth constants, utility helpers, and type aliases (no interfaces)\n- Convert login and setup UIs to TypeScript and keep form state local to each component for readability and component-level ownership\n- Add explicit API payload typing and safe JSON parsing helpers to improve resilience when backend responses are malformed or incomplete\n- Centralize error fallback handling for auth requests to reduce repeated logic

- Replace legacy auth entrypoints with the new feature module in app wiring:\n  - App now imports AuthProvider and ProtectedRoute from src/components/auth\n  - WebSocketContext, TaskMasterContext, and Onboarding now consume useAuth from the new typed auth context\n- Remove duplicated legacy auth screens (LoginForm.jsx, SetupForm.jsx, ProtectedRoute.jsx)\n- Keep backward compatibility by turning src/contexts/AuthContext.jsx into a thin re-export of the new provider/hook

Result: auth code now follows a feature/domain structure, is fully typed, easier to navigate, and cleaner to extend without touching unrelated UI areas.

* refactor(AppContent): update MobileNav import path and add MobileNav component

* refactor(DiffViewer): rename different diff viewers and place them in different components

* refactor(components): reorganize onboarding/provider auth/sidebar indicator into domain features

- Move onboarding out of root-level components into a dedicated feature module:
  - add src/components/onboarding/view/Onboarding.tsx
  - split onboarding UI into focused subcomponents:
    - OnboardingStepProgress
    - GitConfigurationStep
    - AgentConnectionsStep
    - AgentConnectionCard
  - add onboarding-local types and utils for provider status and validation helpers

- Move multi-provider login modal into a dedicated provider-auth feature:
  - add src/components/provider-auth/view/ProviderLoginModal.tsx
  - add src/components/provider-auth/types.ts
  - keep provider-specific command/title behavior and Gemini setup guidance
  - preserve compatibility for both onboarding flow and settings login flow

- Move TaskIndicator into the sidebar domain:
  - add src/components/sidebar/view/subcomponents/TaskIndicator.tsx
  - update SidebarProjectItem to consume local sidebar TaskIndicator

- Update integration points to the new structure:
  - ProtectedRoute now imports onboarding from onboarding feature
  - Settings now imports ProviderLoginModal directly (remove legacy cast wrapper)
  - git panel consumers now import shared GitDiffViewer by explicit name

- Rename git shared diff view to clearer domain naming:
  - replace shared DiffViewer with shared GitDiffViewer
  - update FileChangeItem and CommitHistoryItem imports accordingly

- Remove superseded root-level legacy components:
  - delete src/components/LoginModal.jsx
  - delete src/components/Onboarding.jsx
  - delete src/components/TaskIndicator.jsx
  - delete old src/components/git-panel/view/shared/DiffViewer.tsx

- Result:
  - clearer feature boundaries (auth vs onboarding vs provider-auth vs sidebar)
  - easier navigation and ownership by domain
  - preserved runtime behavior with improved readability and modularity

* refactor(MainContent): remove TaskMasterPanel import and relocate to task-master component

* fix: update import paths for Input component in FileTree and FileTreeNode

* refactor(FileTree): make file tree context menu a typescript component and move it inside the file tree view

* refactor(FileTree): remove unused ScrollArea import

* feat: setup eslint with typescript and react rules, add unused imports plugin

* fix: remove unused imports, functions, and types after discovering using `npm run lint`

* feat: setup eslint-plugin-react, react-refresh, import-x, and tailwindcss plugins with recommended rules and configurations

* chore: reformat files after running `npm run lint:fix`

* chore: add omments about eslint config plugin uses

* feat: add husky and lint-staged for pre-commit linting

* feat: setup commitlint with conventional config

* fix: i18n translations
