Fixed KeyError: 'message' in MCP server handler that broke all memory store operations.

Fixed

• Critical Bug: Fixed KeyError: 'message' in MCP server handler (server.py:2118)
  • Issue: #198

  • Fix: Properly handle MemoryService.store_memory() response format
  • Response Messages: Now include truncated content hash for verification

Added

  • 11 test cases covering success, chunked, and error scenarios
  • Specific regression tests for issue #198
