Improve pre-push hook granularity and CI maintenance checks

[Standing-Man]

Background

The current pre-merge CI already has component detection for language-specific jobs, but several checks still run broadly:

• If the files being pushed do not include files relevant to a language/tool, that language/tool hook should not run.
• Check PR Title does not rerun when a PR title is edited.
• common checks in _common.yml always run, even when the changed files cannot affect that check.
• scripts/ci/license-headers.sh still has a Docker fallback for addlicense.

We should tighten CI execution so PRs run the checks that are relevant to the changed files, while preserving dependency-driven coverage for core changes.

Goals

1. Make pre-push hooks run only when the pushed changes include files relevant to that hook.
2. Ensure PR title validation reruns after a PR title is edited.
3. Remove Docker from the license-header check path and evaluate replacing addlicense with HawkEye.
