perf(ci): skip intensive tests for non-code PR changes

Add a check-code-changes job that detects whether a PR contains actual
code changes or only CI/docs/config files (.github/, .claude/, .cursor/,
docs/, README, LICENSE, etc.).

When no code changes are detected, the following jobs are skipped:
- vulnerability-scan (5 Python versions)
- qa-checks-and-unit-tests (5 Python versions)
- integration-tests (per-file matrix)
- async-integration-tests (per-file matrix)

Manual workflow_dispatch always runs everything. PRs with the
run-async-tests label still trigger async tests as before.
