This commit completes the cleanup of Google ADK references after migrating to PydanticAI.
Changes:
- Removed ADK agent implementation (adk_agent.py)
- Removed ADK test files (test_06, test_07, test_10)
- Removed ADK diagnostic files
- Updated config to use pydantic_system_prompt_variant instead of adk_system_prompt_variant
- Updated prompts.py to rename adk_agent to pydantic_agent
- Updated tool registry and tools.py docstrings to remove ADK references
- Added new comprehensive PydanticAI tests (test_06, test_07, test_10)
- Marked legacy ADK functions as deprecated for backwards compatibility
The codebase is now clean and stable with PydanticAI as the primary agent framework.
Docker container builds successfully with no ADK import errors.

Major Changes:
- Replace Google ADK with PydanticAI framework for agent orchestration
- Implement OpenAI-compatible API endpoint for Ollama integration
- Fix streaming response to send deltas instead of cumulative text
- Add /chat/completions route alias for Open-WebUI compatibility
- Enable tool calling with 5 local tools (calculate, date/time utilities)
Architecture:
- Core-AI service: Standalone Python service with PydanticAI agent
- PydanticAI: Uses OpenAI-compatible Ollama API at /v1 endpoint
- Tool Registry: Shared tool system between core-ai and core-api
- Streaming: Fixed async context issues and delta calculation
Verified Working:
✅ Chat completion (streaming & non-streaming)
✅ Tool calling with mistral-nemo and mistral-tools models
✅ Open-WebUI integration via core-ai:8086
✅ 5 tools: calculate, get_current_time, get_current_date, calculate_date_difference, add_days_to_date
✅ Proper streaming deltas (no repetition)
Technical Details:
- PydanticAI 1.25.0+ with full Ollama support
- Async context manager issue resolved via chunk collection
- Delta calculation: chunk[len(previous):] to extract new content only
- Routes: /v1/chat/completions and /chat/completions (Open-WebUI compat)
