Context Propagation And Isolation Across Tool Invocations

MCP session management for Metorial. Provides session handling and tool lifecycle management for Model Context Protocol.

Unique: Uses async-local storage to bind context to the execution stack of tool handlers, providing automatic context propagation without explicit parameter threading. Context is automatically inherited by nested async operations within a tool invocation.

vs others: More elegant than manual context threading (passing context as parameters) and more reliable than global variables because it provides true isolation between concurrent invocations without race conditions.
