What
The function that decides whether the SDK needs to re-send its 'system/init' bridge announcement now also factors in the sorted list of non-terminal MCP command names, in addition to the model, permission mode, fast-mode, and effort settings it already checked.
Why
This means that if the set of available MCP commands changes during a session, SDK-connected clients are now notified via a fresh announcement, keeping their view of available commands in sync.
