fix: Use timezone.utc instead of UTC for Python 3.10 compatibility

The UTC constant was added in Python 3.11. Changed to use
timezone.utc which is available in Python 3.10+.

Fixed ImportError: cannot import name 'UTC' from 'datetime'

fix: Resolve database connection and episode processing errors

Fixed two critical runtime errors:

1. Database connection check for KuzuDB
   - KuzuDB session.run() returns None, causing async iteration error
   - Added special handling for KuzuDB (in-memory, no query needed)
   - Other databases (Neo4j, FalkorDB) still perform connection test

2. Episode processing parameter error
   - Changed 'episode_type' parameter to 'source' to match Graphiti API
   - Added required 'reference_time' parameter with current timestamp
   - Added datetime imports (UTC, datetime)

Errors fixed:
- 'async for' requires an object with __aiter__ method, got NoneType
- Graphiti.add_episode() got an unexpected keyword argument 'episode_type'

feat: MCP Server v1.0.0rc0 - Complete refactoring with modular architecture

This is a major refactoring of the MCP Server to support multiple providers
through a YAML-based configuration system with factory pattern implementation.

## Key Changes

### Architecture Improvements
- Modular configuration system with YAML-based settings
- Factory pattern for LLM, Embedder, and Database providers
- Support for multiple database backends (Neo4j, FalkorDB, KuzuDB)
- Clean separation of concerns with dedicated service modules

### Provider Support
- **LLM**: OpenAI, Anthropic, Gemini, Groq
- **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
- Comprehensive test suite with unit and integration tests
- GitHub Actions workflows for linting and testing
- Multi-database testing support

### Docker Support
- Updated Docker images with multi-stage builds
- Database-specific docker-compose configurations
- Persistent volume support for all databases

### Bug Fixes
- Fixed KuzuDB connectivity checks
- Corrected Docker command paths
- Improved error handling and logging
- Fixed boolean environment variable expansion
