/**
* In-memory implementation of MCP server configurations cache for single-instance deployments.
* Uses a native JavaScript Map for fast, local storage without Redis dependencies.
* Suitable for development environments or single-server production deployments.
* Does not require leader checks or distributed coordination since data is instance-local.
* Data is lost on server restart and not shared across multiple server instances.
