feat(ci): split code quality into 4 parallel jobs

Split the single prek job into parallel jobs:
- pre-commit-hooks: lightweight hooks (SKIP=poe-check)
- package-checks: fmt/lint/pyright/mypy via check-packages
- samples-markdown: samples-lint, samples-syntax, markdown-code-lint
- mypy: change-detected mypy checks

All 4 jobs run concurrently (×2 Python versions = 8 runners).
