/**
 * Bun dev server runner — `@pikku/bun-server` (native `Bun.serve` WebSockets).
 * Used when the CLI runs under Bun. The bun-server module is dynamically
 * imported so a node-run CLI never loads its bun-only code; types are pulled via
 * `import type` (erased at runtime). The same BunEventHubService instance is
 * shared with singleton services so function-side broadcasts reach the sockets
 * the transport holds.
