fix: update pnpm version to 10 to match lockfile format

- Changed pnpm version from 9 to 10 in workflow
- Added run_install: false to prevent automatic installation
- Local environment uses pnpm 10.24.0 which generated the lockfile
- Resolves: ERROR packages field missing or empty during pnpm install
