fix(ci): repair github node 24 workflows

Install pnpm before enabling setup-node's pnpm cache in the Cloudflare deploy job, and make the Node 24 check workflow self-contained by providing the public build URLs directly.

These fixes address the first GitHub-hosted failures that surfaced after the Node 24 migration push without changing the application runtime.
