Pull request overview

Lazy-initializes the shared Langfuse client to avoid import-time side effects (e.g., requiring env vars at import), and allows Configs to tolerate unknown environment variables via extra="ignore".

Changes:

• Refactored shared_client.py and __init__.py to use cached_property and module-level __getattr__ for lazy Langfuse client creation.
• Added extra="ignore" to the pydantic Configs settings so unknown env vars are silently skipped.
• Bumped aieng-agents from 0.1.0 → 0.1.1.
