What

The internal function used to send local/remote-control messages now accepts a fromPlugin option, which stamps outgoing messages with a from_plugin field.

Why

This lets Claude Code track which messages sent between sessions originated from a plugin, which other changes in this release rely on to pass that origin information along.
