Server Architecture Refactoring - Phase 1

This release improves code maintainability by extracting 453 lines from monolithic server.py into a modular server/ package with 4 focused modules.

What's New

Modular Server Package

• client_detection.py (76 lines) - MCP client detection logic
• logging_config.py (77 lines) - Client-aware logging configuration
• environment.py (189 lines) - Environment setup and validation
• cache_manager.py (111 lines) - Global cache management

Code Improvements

• Reduced Complexity: server_impl.py shrunk from 4,613 to 4,293 lines (-320 lines, -7%)
• Better Organization: Related functionality grouped into focused modules
• Backward Compatibility: All existing imports preserved via server/init.py

Quality Metrics

• Max complexity: 6/10 (below threshold of 8)
• Security issues: 0
• Health score: ~85/100 (Excellent)
• All tests passing

Why This Matters

The original server.py at 4,613 lines was becoming difficult to maintain and navigate. This refactoring:

• Makes the codebase more approachable for new contributors
• Simplifies future feature additions
• Improves code discoverability and organization
• Sets the foundation for Phases 2 and 3

Next Steps

This is Phase 1 of a 3-phase refactoring plan:

• Phase 1: Extract utilities into modules (completed)
• Phase 2: Extract handlers into separate module
• Phase 3: Core MemoryServer refactoring

Related Issues

• Progresses #291 (server.py refactoring project)

Installation: pip install --upgrade mcp-memory-service

Note: This is an internal architecture improvement with no user-facing changes. All existing functionality remains unchanged.
