refactor(core-ai): comprehensive cleanup - PydanticAI only architecture
Remove all obsolete agent implementations and framework references.
Keep only PydanticAI (primary) and SimpleLiteLLM (fallback).
This cleanup eliminates confusion between multiple frameworks that were
tried during development (LangChain, LangGraph, ADK, OllamaNative) and
establishes PydanticAI as the single agent framework going forward.
BREAKING CHANGES:
- Removed OllamaNativeAgent - use PydanticAgent instead
- Removed /test/ollama-tools diagnostic endpoint
- Default /v1/chat/completions now uses PydanticAgent
