Fix CI matrix and pnpm cache: set env vars in workflow, drop matrix

- Set PNPM_STORE_DIR and COREPACK_HOME as job env vars instead of
  relying on container.options -e flags which act_runner may ignore
- Replace fragile cross-job matrix with single-job loop for builds
- Both fixes: empty matrix app name and 0 reused packages
