doc-policy-lint.test.mjs fails locally on Windows (vitest SyntaxError), green in CI

• severity: low
• file: C:\GitHub\github-workflows\scripts\doc-policy-lint.test.mjs (origin/main, added in feat(lint): add warning-only doc-policy lint #76 / d43a255)
• context: npx vitest run reports "SyntaxError: Invalid or unexpected token" loading the suite (0 tests) on Windows, yet node --check passes and the self-test.yml job (ubuntu/node20, npm test) is green on the same commit. Almost certainly a CRLF/encoding sensitivity in the test (or a fixture it reads) that only bites on Windows checkouts. Discovered incidentally during label-seed work (Expand standard label seed: close automation gaps + add common defaults #87); unrelated to that change.
