Tai Groot 33fd98d746 feat: add commit-msg hook, improve robustness
- Add commit-msg hook enforcing Conventional Commits format
  (allows merge, fixup, and squash commits)
- Fix file size display: use MiB (binary) to match the binary limit calculation
- Make gitleaks optional: skip gracefully if not installed
- Suppress stderr on mg register in pre-push
- Add shellcheck directive to pre-commit
- Mark gitleaks as optional in README prerequisites
- Clean up FUNDING.yml boilerplate
