📝 Walkthrough

Walkthrough

This PR introduces a context-driven desktop application architecture with centralized state management. It adds CI/CD workflows, updates ESLint configuration, creates context providers and hooks for file system and window management, refactors components to use context instead of props, and adds error boundary handling for robustness.

Changes

Cohort / File(s)	Summary
Build & Configuration .github/workflows/ci.yml, eslint.config.mjs, package.json	Added GitHub Actions CI workflow for Node.js 20 with lint and typecheck; new ESLint configuration supporting TypeScript, JSX, and Next.js with React hooks; updated npm scripts and dev dependencies for eslint-plugin-react-hooks and globals.
Context & State Management src/context/DesktopContext.tsx, src/hooks/use-file-system.ts, src/hooks/use-window-manager.ts, src/hooks/use-command-handler.ts	Introduced DesktopProvider that composes file system and window manager contexts; new useFileSystem hook with localStorage persistence, CRUD operations, and toast notifications; new useWindowManager hook managing draggable/minimizable windows with zIndex and lock states; enhanced useCommandHandler with about, skills, projects, and contact commands.
File System Library src/lib/file-system.ts	Replaced TypeScript interfaces with Zod runtime schemas (FileSchema, DirectorySchema) for validation; enables type-safe file system operations across the app.
Main Page & Desktop Components src/app/page.tsx, src/components/desktop/*	Refactored page.tsx from monolithic state to context-driven DesktopProvider architecture; updated app-gallery, dock, file-explorer, music-player, and settings components to accept minimal props and derive state from useFileSystemContext and useWindowManagerContext; reorganized app registry with BASE_APPS manifest; exported AppId, App, and WindowInstance types.
UI Components src/components/ui/error-boundary.tsx, src/components/desktop/window.tsx, src/components/desktop/top-bar.tsx	Added ErrorBoundary class component for error handling with fallback UI and stack trace logging in development; wrapped window content with ErrorBoundary; converted TopBar to React.memo for optimization; integrated useWindowManagerContext import.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~50 minutes

This PR involves substantial architectural restructuring with high logic density, affecting configuration, new context/hook systems, and multiple component refactors across diverse file types. The heterogeneous nature of changes (new files, hooks, refactored components, state management patterns) and the coordination between context providers and consuming components require careful cross-file analysis.

Poem

🐰 hops with glee

Context flows through every leaf,
From provider down to belief!
States now dance in harmony,
No props cascade—just purity.
whiskers twitch A desktop anew! 🖥️✨
