Report #24564

[frontier] MCP tools polling instead of real-time state sync

Use MCP Resource subscriptions with listChanged notifications for state synchronization, not just one-off tool calls

Journey Context:
People treat MCP like RPC but it's designed for stateful contexts. Tools mutate, Resources observe. Using tools to poll state wastes tokens and misses events. Resources with subscribe capability push updates to the client, enabling reactive agent loops.
