Detect license and notice issues in GitHub CI

### Is your feature request related to a problem? Please describe.

License and notice issues in bundled artifacts can slip through until late review, risking incorrect LICENSE or NOTICE files in releases.

### Describe the solution you'd like

Add a GitHub CI check to validate license and notice files for built artifacts.

The check should fail when:
- required files(e.g., License, notice) are missing
- bundle license or notice content is incorrect or outdated
- dependencies are missing or stale in the bundle files

### Describe alternatives you've considered

### Additional context

_No response_

Start by reviewing the repository's GitHub CI workflows and the process that produces built artifacts, then identify where LICENSE, NOTICE, and dependency bundle files are assembled. Define checks for missing, incorrect, outdated, or stale contents, and add CI coverage for each failure case. Done means the workflow reliably rejects invalid bundles and passes for valid artifacts.
