ci: Enable workflow on feature branches and pull requests

Update GitHub Actions workflow to trigger on:
- Pushes to main branch
- Pushes to claude/** feature branches
- Pull requests targeting main branch

This ensures the build workflow runs for all development branches
and pull requests, not just main branch commits.
