/**
 * Verify that the Python single-exe deploy manifest explicitly supplies every
 * required workspace peer of every workspace package in its dependency graph.
 *
 * `pnpm deploy --config.auto-install-peers=false` cannot repair an incomplete
 * runtime root. Keeping the peer at the root also prevents a successful build
 * from producing an executable that fails only when Cordis loads the plugin.
