build: convert repo from npm to pnpm

- replace package-lock.json with pnpm-lock.yaml (via pnpm import)
- add packageManager field (pnpm@11.15.1)
- convert npm-isms in package.json scripts and husky pre-commit hook
- CI: add pnpm/action-setup@v6, cache pnpm, pnpm install --frozen-lockfile, bump codecov-action to v7
- ignore yarn.lock; skip formatting pnpm-lock.yaml
