[CI] Gate pre-commit on ready label or number of contributions

[hmellor]

pre-commit is experiencing a lot of congestion. This PR should ease the congestion by only running pre-commit:

• for contributors with 4 or more merged PRs
• for PRs with the ready label

This change should:

• be invisible to regular contributors
• allow maintainers to manually enable the check for new contributors/bots

Hi @hmellor, the pre-commit checks have failed. Please run:

uv pip install pre-commit>=4.5.1
pre-commit install
pre-commit run --all-files

Then, commit the changes and push to your branch.

For future commits, pre-commit will run automatically on changed files before each commit.

Tip

Is mypy failing?

mypy is run differently in CI. If the failure is related to this check, please use the following command to run it locally:

# For mypy (substitute "3.10" with the failing version if needed)
pre-commit run --hook-stage manual mypy-3.10
