feat: Major MCP server refactor with improved structure and CI/CD
- Reorganized MCP server into clean, scalable directory structure:
- `src/config/` - Configuration modules (schema, managers, provider configs)
- `src/services/` - Services (queue, factories)
- `src/models/` - Data models (entities, responses)
- `src/utils/` - Utilities (formatting, helpers)
- `tests/` - All test files
- `config/` - Configuration files (YAML, examples)
- `docker/` - Docker setup files
- `docs/` - Documentation
- Added `main.py` wrapper for seamless transition
- Maintains existing command-line interface
- All deployment scripts continue to work unchanged
- **Queue Service Interface Fix**: Fixed missing `add_episode()` and `initialize()` methods
- Server calls at `graphiti_mcp_server.py:276` and `:755` now work correctly
- Eliminates runtime crashes on startup and episode processing
- Updated imports throughout restructured codebase
- Fixed Python module name conflicts (renamed `types/` to `models/`)
- **MCP Server Tests Action** (`.github/workflows/mcp-server-tests.yml`)
- Runs on PRs targeting main with `mcp_server/**` changes
- Configuration validation, syntax checking, unit tests
- Import structure validation, dependency verification
- Main.py wrapper functionality testing
- **MCP Server Lint Action** (`.github/workflows/mcp-server-lint.yml`)
- Code formatting with ruff (100 char line length, single quotes)
- Comprehensive linting with GitHub-formatted output
- Type checking with pyright (baseline approach for existing errors)
- Import sorting validation
- Added ruff and pyright configuration to `mcp_server/pyproject.toml`
- Proper tool configuration for the new structure
- Enhanced development dependencies with formatting/linting tools
- All existing tests moved and updated for new structure
- Import paths updated throughout test suite
- Validation scripts enhanced for restructured codebase
- **Improved Maintainability**: Clear separation of concerns
- **Better Scalability**: Organized structure supports growth
- **Enhanced Developer Experience**: Proper linting, formatting, type checking
- **Automated Quality Gates**: CI/CD ensures code quality on every PR
- **Zero Breaking Changes**: Maintains full backwards compatibility
