* feat(skills): make tdd-workflow test-runner aware (npm/pnpm/yarn/bun)
Add "Step 0: Detect the Test Runner" so the RED/GREEN cycle no longer
hardcodes `npm test`. Distinguishes the package manager from the test
runner (a project can install with Bun yet run Jest/Vitest), adds a runner
command matrix, and warns about `bun test` (native bun:test runner) vs
`bun run test` (runs the package.json script) — a common ESM failure mode.
Adds a Bun native test pattern section and links the bun-runtime skill.
Applied to both the canonical skills/ copy and the .agents/skills/ Codex
subset (manual sync per CONTRIBUTING).
* docs(skills): apply <test>/<coverage> placeholders in tdd-workflow steps
Address review feedback on PR #2347: Step 0 instructs the agent to substitute
the detected runner command, but Steps 3/5/7, Run Coverage Report, Watch Mode,
Pre-Commit, and CI/CD still showed literal `npm test` / `npm run test:coverage`
— so an agent reaching those blocks could run npm test on a pnpm/bun project.
Replace them with the <test> / <test-watch> / <coverage> placeholders from
Step 0. Left untouched: the plan-handoff allowlist example and the Step 8
evidence-table samples (illustrative, not run-this instructions). Applied to
both the canonical and Codex-subset copies.
* docs(skills): make pre-commit lint runner-agnostic via <lint> placeholder
Follow-up to PR #2347 review (CodeRabbit): the pre-commit example still used
`npm run lint`, coupling it to npm after test/coverage were made runner-aware.
Add a `<lint>` column to the Step 0 runner matrix (npm run lint / pnpm lint /
yarn lint / bun run lint) and change the Pre-Commit Hook example to
`<test> && <lint>`. Applied to both the canonical and Codex-subset copies.
* chore: re-trigger CI (flaky windows/node20 npm cell)
