Mohamed Boudra 37ac245f8c fix(plugins): a kept command honors the composer lock, and useAgent metadata is frozen
A plugin action that awaits an RPC holds the composer it was created with. The lock was captured
at that render, so a submit that started meanwhile did not stop its insertText. Commands now ask
the composer whether it is locked when they run.

The agent snapshot a plugin gets from useAgent froze only the outer metadata record. It now uses
the same deep frozen copy as the composer.
