Add automated test suite for regression detection and performance tracking
of the core-ai agent behavior across code changes.
Changes:
- Add test_ai_flow_quality.py with 5 core test scenarios
- Simple knowledge queries (no tools)
- Web search integration
- Mathematical calculations
- Date/time operations
- Multi-tool reasoning tasks
- Add QUALITY_TESTS.md documentation
- Usage guide and test descriptions
- Baseline establishment workflow
- Model benchmarking procedures
- Troubleshooting guide
- Add performance baseline tests
- Add regression detection tests
- Generate text and JSON reports with git tagging
- Update .gitignore to exclude generated test reports
- Update CHANGELOG.md with test suite details
Baseline Results:
- 4/5 tests passing (80% success rate)
- Average response time: 2-8s per query
- Agent: OllamaNativeAgent with PydanticAI
- Model: mistral-nemo:latest

Problem:
- Model was hallucinating time answers (e.g., wrong Amsterdam time)
- get_current_time() only returned UTC
- No way to query time in specific timezones
Solution:
- Enhanced get_current_time(timezone) to support any IANA timezone
- Added pytz>=2025.2 dependency for timezone handling
- Returns formatted time with timezone info: "2025-11-30 16:25:55 CET"
- Supports timezones: Europe/Amsterdam, America/New_York, Asia/Tokyo, etc.
Testing:
- Added test_timezone.py: 6 comprehensive timezone tests
- UTC, Amsterdam, New York, Tokyo timezone queries
- Invalid timezone error handling
- Timezone offset correctness validation
- Added test_agent_timezone.py: 3 integration tests
- Agent tool usage for timezone queries
- Agent behavior with/without tools
- Multi-timezone query handling
All new tests passing. Tool verified working across multiple timezones.

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)
