Add GitHub Actions workflow for pull request checks #30
Description
The repository currently has no automated pull request checks, which allows
broken or unverified code to be merged.
This issue proposes adding a GitHub Actions workflow that runs on pull requests
to validate code quality and build integrity.
The PR checks workflow should:
- Trigger on pull_request events.
- Install project dependencies.
- Run linting (ESLint).
- Run a production build to ensure it succeeds.
- Fail the PR if any step fails.
Benefits:
- Prevents broken builds from being merged.
- Improves confidence during code reviews.
- Establishes a CI baseline for future workflows.
This workflow will serve as the foundation for additional CI automation.
