Is your feature request related to a problem?

Yes. TBD:
Currently, developers can inadvertently merge TODO comments into the production main branch. These TODO comments are useful during development but should not be present in the production code.

Describe the solution you'd like

We need a GitHub (later also GitLab) Action that allows TODO comments in the development branches but issues a warning or fails the build if TODO comments are present when merging into the production main branch.

Describe alternatives you've considered

No response

Additional context

We are specifically targeting our TODO convention, not others by default.
And we suggest converting these into GitHub Issues or Jira Tasks using the information from the metadata.
