Merge branch 'main' into atif/validate-readme-source

- Use more specific regex pattern [a-zA-Z0-9-]+ instead of [^/]+ for namespace/module names
- Process all Terraform blocks instead of just the first one
- Report correct source if found in any block, only report incorrect sources if no correct source exists
- Add comprehensive test cases for multiple Terraform blocks
