/**
 * 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., @anthropic-ai/sdk,
 * openai) at startup. The loaded module promise is cached so subsequent calls
 * reuse the same import.
 *
 * stream.ts imports its provider stream functions from this module (see the
 * lazy wrappers below), so this file IS the main streaming path's provider
 * loader: heavy SDKs stay out of the CLI startup parse graph.
