chore: migrate from npm to pnpm

- Add packageManager field (pnpm@9.15.9) to package.json
- Replace npm commands with pnpm in scripts
- Move overrides to pnpm.overrides format
- Create .npmrc with shamefully-hoist for Angular compatibility
- Update CI and Deploy workflows to use pnpm/action-setup
- Replace package-lock.json with pnpm-lock.yaml
- Update README with pnpm instructions
