Channel lazy load: discover_enabled() only imports enabled channel modules instead of all 18 modules with heavy SDKs (telegram, discord, slack, etc). discover_all() now delegates to discover_enabled(). Lazy OpenAI client: defer AsyncOpenAI() + httpx construction to _ensure_client() with asyncio.Lock double-checked locking. openai and httpx imports moved from module-level into _ensure_client(). Minor: lazy Nanobot/RunResult and CronService exports via __getattr__. Benchmark: 6910ms → 460ms (-93.3%)
