jif 79177c3e20 Propagate deferred environment capability roots to MCP (#33427) ...

## What changed

- Let deferred environments provide selected capability roots with their ready signal.
- Validate that those roots have unique, non-empty IDs, belong to the registering environment, and stay within the root limit.
- Include roots from ready turn environments when resolving MCP contributions, and refresh the MCP runtime when the selected root set changes.
- Expose the exact ready root set to MCP contributors so executor plugins become available with their environment.

## Testing

- Cover ready-root propagation, validation failures, replacement isolation, reconnection, and MCP plugin availability refresh.
