Removed all remaining Kuzu references from:
- Test fixtures (test_fixtures.py): Changed default database to falkordb, removed kuzu configuration
- Test runner (run_tests.py): Removed kuzu from database choices, checks, and markers
- Integration tests (test_comprehensive_integration.py): Removed kuzu from parameterized tests and environment setup
- Test README: Updated all examples and documentation to reflect falkordb as default
- Docker README: Completely rewrote to remove KuzuDB section, updated with FalkorDB combined image as default
All Kuzu support has been completely removed from the MCP server codebase. FalkorDB (via combined container) is now the default database backend.

- **Embedders**: OpenAI, Voyage, Gemini, Anthropic, Sentence Transformers
- **Databases**: Neo4j, FalkorDB, KuzuDB (new default)
- Azure OpenAI support with AD authentication
### Configuration
- YAML configuration with environment variable expansion
- CLI argument overrides for runtime configuration
- Multiple pre-configured Docker Compose setups
- Proper boolean handling in environment variables
### Testing & CI
