Zero-config linting and formatting for JavaScript/TypeScript with pluggable linter backends.

• Supports three linter backends: Biome (recommended), ESLint + Prettier, and Oxlint + Oxfmt; auto-detects active linter from config files
• CLI commands for checking issues, auto-fixing, diagnosing setup problems, and initializing new projects with interactive or non-interactive modes
• Framework-specific presets available for React, Next, Vue, Svelte, Angular, Astro, NestJS, and others; extends via config files
• Enforces consistent code standards covering formatting (2-space indent, semicolons, 80-char width), style (arrow functions, const-first, template literals), and correctness (no unused imports, no any types, exhaustive React deps)
