- Introduces the `RDIFF_ACCEPT_NEW_GOLDENS` commit message tag. - Conditionally skip the `test-renderdiff` presubmit comparison if this tag is present. - Extracts renderdiff generation into a reusable `.github/actions/renderdiff-generate` composite action. - Modifies `postsubmit-main.yml` to automatically generate new goldens and push them to a temporary `accept-goldens-<short-hash>` branch before merging them into `main` when the tag is found.
