Docs-only PRs (only .md files and docs/ changes) now skip the expensive
build, typecheck, and test jobs while still running lint and a new
docs-check job. The docs-check job runs a prompt injection scanner that
detects hidden directives, role overrides, system prompt markers, tool
call injection, and invisible Unicode in markdown prose (excluding
fenced code blocks and inline code spans).
