feat(ci): expand cache paths to support all Node.js package managers

- Add comprehensive caching for npm, yarn, and pnpm package managers
- Cache paths now include:
  - npm: ~/.npm, node_modules/.cache
  - yarn: ~/.yarn, ~/.cache/yarn, ~/.cache/yarn/global
  - pnpm: ~/.pnpm-store, ~/.cache/pnpm, ~/.local/share/pnpm/global
- Update cache keys to include all lockfile types (package-lock.json, yarn.lock, pnpm-lock.yaml)
- Rename 'Cache Tree-sitter CLI' to 'Cache npx store' for clarity
- Apply changes consistently across test, lint, and coverage jobs

This improves cache hit rates and build performance regardless of which
Node.js package manager is used in the development environment.
