[tooling] Agent wastes tokens polling MCP tools to check for updated data

Expose the data as an MCP Resource with a stable URI and use resources/subscribe; server pushes updates only on changes

Journey Context:
Agents often implement polling loops calling 'get\_status' tools repeatedly, burning tokens on every check. MCP Resources support persistent URIs and subscription notifications \(notifications/resources/updated\). By modeling quasi-static state as resources instead of tools, the agent eliminates polling logic and receives push updates only when data actually changes, cutting token usage by avoiding unnecessary round-trips and JSON parsing.
