What changes will this PR take into?

This PR strengthens the CI pipeline by enforcing linting, formatting, and type-safety standards. It ensures that any code pushed to the repository is consistent with the project's style guidelines and free of architectural TypeScript errors.

Key features:

1. Automated Format Enforcement: The workflow runs pnpm lint:fix and fails if any tracked files are modified. This ensures that all submitted code is perfectly formatted.
2. Type Safety Integration: Added a mandatory pnpm exec tsc -b step to verify TypeScript compilation and catch errors that ESLint might overlook.
3. Optimized CI Workflow:
   • Uses Node 22 to match the project's test environment.
   • Ignores untracked files in the format check to prevent false positives.
   • Aligns with existing project standards by using consistent Action versions (@v6).
