jif ef2d3edb95 Prewarm MCP runtime updates in the background (#35144) ...

## Why

Changes to MCP inputs can require rebuilding the runtime before the next model
step. Start that work eagerly so the step is less likely to wait for it.

## What changed

- Add a per-session worker that prewarms dirty MCP state after configuration,
  authentication, or explicit refresh changes.
- Coalesce queued refreshes and always rebuild from the latest session state,
  while keeping exact model-step refreshes as the correctness path.
- Stop and join the worker during session shutdown.

## Testing

- Verify rapid refreshes skip superseded configuration and publish the latest
  state.
- Verify MCP-relevant policy changes mark the runtime for refresh.
