Accept normalized CLA signature comments

[glenn-jocher]

Valid CLA signature comments with trailing whitespace or surrounding Markdown currently never reach the normalized action matcher because the workflow gate requires exact equality.

This makes only the signature gate permissive. The recheck command remains exact, and the action still decides whether a single normalized line is a valid signature, so quoted or instructional text does not sign the CLA.

Validation:

• actionlint .github/workflows/cla.yml
• npx prettier@3.8.5 --check .github/workflows/cla.yml

🌟 Summary

Updated the CLA workflow to pass comments containing the valid signature phrase to the normalized action matcher instead of requiring exact comment equality.

📊 Key Changes

• Changed the signature check in .github/workflows/cla.yml from exact equality to contains(...).
• Kept the recheck command matched by exact equality.
• Left final signature validation to the CLA action, which determines whether the normalized content is a valid signature.

🎯 Purpose & Impact

• CLA signature comments with trailing whitespace or surrounding Markdown can now trigger the CLA workflow and reach normalized validation, while quoted or instructional text remains subject to the action’s signature checks.

LGTM. The workflow gate is intentionally broadened only for signature-comment detection, while the exact recheck command remains unchanged. The action retains responsibility for validating a normalized signature line, so surrounding instructional or quoted text does not sign the CLA.

This focused CLA workflow update allows comments containing valid signature phrases—including trailing whitespace or surrounding Markdown—to reach normalized validation, while preserving exact recheck matching and the CLA action’s final signature checks.
