# Install all workspace deps, then flatten broker's prod subset into /deploy.
# pnpm deploy: resolves workspace:* to real copies, drops catalog: references,
# drops devDependencies (--prod), produces a self-contained runtime directory
# with only what this one package + its transitive prod deps need.
