Pull request overview

This PR narrows the CI workflow trigger so it only runs for pull requests that touch the project’s Lua code and related runtime/test directories, reducing unnecessary CI runs for unrelated changes.

Changes:

• Added pull_request.paths filters to only trigger CI when files under lua/**, plugin/**, or tests/** change.

• Same as for push: the pull_request.paths filter currently excludes root tool config files like stylua.toml and .luacheckrc. Changes to those files won’t trigger CI on PRs, so formatting/lint behavior could change without checks running. Add the relevant config files to this path list too.

    paths:
      - 'lua/**'
      - 'plugin/**'
      - 'tests/**'
      - '.github/workflows/**'
      - 'Makefile'
