Add CI enforcement of conventional commit format for PR titles and
commit messages. Includes three Python scripts under Tools/ci/:
- conventional_commits.py: shared parsing/validation library
- check_pr_title.py: validates PR title format, suggests fixes
- check_commit_messages.py: checks commits for blocking errors
(fixup/squash/WIP leftovers) and advisory warnings (review-response,
formatter-only commits)
The workflow (.github/workflows/commit_checks.yml) posts concise
GitHub PR comments with actionable suggestions and auto-removes them
once issues are resolved.
Also updates CONTRIBUTING.md and docs with the conventional commits
convention.

In CONTRIBUTING.md, the current link to the coding style leads to a
404 error. I've replaced it with a link to the Source Code Management
part of the developer documentation, which is where the style guide
seems to be now.
