ci(deploy): fix workers build install

[Tuxedolphin]

Summary

• add the required non-empty packages field to frontend/pnpm-workspace.yaml for Cloudflare's pnpm 10 install step
• update Workers Builds docs to use pnpm build because Cloudflare installs dependencies before running the build command

Cloudflare failure addressed

Cloudflare failed during its dependency install phase with:

ERROR packages field missing or empty

The workspace file previously only contained allowBuilds, which local pnpm 11 tolerated but Cloudflare's detected pnpm 10.11.1 rejected.

Verification

• clean temp install with npx --yes pnpm@10.11.1 install --frozen-lockfile
• pnpm build
• npx --yes wrangler@latest deploy --dry-run
• git diff --check
• diff scan for token and generated attribution strings
