Sandbox status data format bumped from version 2 to version 3

What

The internal payload describing a sandbox's status (the isolated environment Claude Code can run commands in) now reports statusVersion: 3 instead of 2.

Why

This signals a change in the shape or contents of the sandbox status data; the version bump itself doesn't change visible behavior.
