/**
 * Lazy provider module loading.
 *
 * Each provider module is loaded only when its stream function is first called.
 * This avoids eagerly importing heavy SDK dependencies (e.g., openai) at
 * startup. The loaded module promise is cached so subsequent calls
 * reuse the same import.
 *
 * NOTE: stream.ts currently imports providers directly, so this file is not yet
 * wired into the main streaming path. It provides the infrastructure for lazy
 * loading that can be integrated when stream.ts is refactored.
