[frontier] How to dynamically update relevant file context for MCP servers without reinitializing connections

Use MCP Roots to dynamically notify servers of currently relevant resources; update roots client-side when user context switches \(e.g., changing files in IDE\) to trigger server-side re-evaluation of available resources without re-initializing the MCP session

Journey Context:
Traditional MCP servers are stateless and re-scan resources on init. For IDE agents, when user switches from file A to file B, the server needs to know file B is now relevant without full re-init \(which breaks conversation history\). MCP Roots allow clients to push scope changes dynamically. Alternative: server polls filesystem continuously \(inefficient, laggy\) or full re-init \(breaks context\). This is correct because it enables real-time context synchronization with minimal overhead while preserving conversation state.
