feat: move from mozilla any-agent to langchain deepagents

Confidence Score: 4/5

The migration is architecturally sound and well-tested, but the extract_document_data tool in toolset.py will crash at runtime whenever document extraction is triggered.

LangGraph's sync invoke() runs async graphs via an internal event loop. A tool called from inside that loop cannot call asyncio.run() without raising RuntimeError: This event loop is already running. The extract_document_data tool in toolset.py does exactly this (line 511), so every model-initiated PDF/image extraction will fail. All other changed paths are clean.

ask_alyf/ask_alyf/toolset.py — the extract_document_data method needs to run tools.extract_document_data in a worker thread rather than calling asyncio.run() directly.
