pnpm fetch in pnpm 11.10.0 tries to apply patches during the fetch phase,
failing because packages aren't installed to node_modules yet.
Consolidated back to COPY . . + pnpm install.
Also bumps: docker/dockerfile 1.10->1.25, typescript ^6->^7,
actions/cache@v4->v6, actions/upload-artifact@v4->v7,
actions/github-script@v8->v9
