Infrastructure Layer Filesystem Operations With Error Handling

A Model Context Protocol (MCP) server implementation for remote memory bank management, inspired by Cline Memory Bank.

Unique: Implements filesystem operations as concrete implementations of data access interfaces rather than scattered throughout application, enabling centralized error handling and potential future storage backend swapping

vs others: More maintainable than scattered filesystem calls because all I/O is centralized in Infrastructure layer, whereas ad-hoc filesystem calls throughout the codebase are harder to test and modify
