Add build and test checks to pre-commit hooks

[bhouston]

Description

This PR enhances the pre-commit hooks to include build and test checks, preventing commits that would break the build or fail tests.

Changes

• Updated the pre-commit hook to run pnpm build and pnpm test before allowing commits
• Updated the CONTRIBUTING.md documentation to reflect these changes

Testing

• Tested the pre-commit hook locally to ensure it correctly prevents commits when builds fail or tests don't pass
• Confirmed that the hook allows commits when all checks pass

Note

There's a Husky deprecation warning about the shebang and source line that will need to be addressed in a future update when upgrading to Husky v10.0.0.
