Feature/validate filename

[lachlan-robinson]

Description

This workflow introduces an automated validation step for pull requests that checks all changed filenames for the presence of a colon (:). If any filenames contain a colon, the workflow will:

1. Fail the pull request check, preventing merge until the issue is resolved.
2. Post a comment directly on the pull request, listing the offending filenames and instructing contributors to rename them.

This ensures filename conventions are enforced consistently across the repository and prevents potential issues with file handling on different systems.

Fixes # (issue)

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation (update or new)

How Has This Been Tested?

The workflow was tested by opening a pull request with files containing : in their names.

• When such files were detected, the workflow failed and a comment was automatically posted to the PR.
• When no such files were present, the workflow passed successfully and no comment was left.

Hello @lachlan-robinson,

Thank you for this addition; it’s a very welcome improvement, as it helps prevent Git from breaking on Windows. I’ve reviewed the implementation and am very happy with how it’s been done.

I appreciate the opportunity to review your work and great job on this
