Thanks @tdavidcl for opening this PR!

You can do multiple things directly here:
1 - Comment pre-commit.ci run to run pre-commit checks.
2 - Comment pre-commit.ci autofix to apply fixes.
3 - Add label autofix.ci to fix authorship & pre-commit for every commit made.
4 - Add label full-ci to run the full test suite (default is light CI; full CI also runs on Mergify merge-queue branches).
5 - Add label profile-build to run the compile-time build profile job even in light CI.
6 - Add label trigger-ci to create an empty commit to trigger the CI.

Once the workflow completes a message will appear displaying informations related to the run.

Also the PR gets automatically reviewed by gemini, you can:
1 - Comment /gemini review to trigger a review
2 - Comment /gemini summary for a summary
3 - Tag it using @gemini-code-assist either in the PR or in review comments on files

Commiter email is 41898282+github-actions[bot]@users.noreply.github.com
You are using github private e-mail. This prevent proper tracing of who contributed what, please disable it (see Keep my email addresses private).

Light CI is enabled (the default for pull requests). This will only run the basic tests and not the full tests.
Full CI runs if the full-ci label is set, or automatically on Mergify merge-queue branches (mergify/merge-queue/*).
The merge gate job "on PR / all" is skipped in this case. Queue entry uses "on PR / all_light"; full CI runs in the merge queue.
