/**
* Sidebar prompt injection defense tests
* Current terminal-sidepanel security boundary.
*
* Validates: XML escaping, command allowlist in system prompt,
* Opus model default, and sidebar-agent arg plumbing.
* Detailed PTY lifecycle behavior has dedicated tests. These source contracts
* instead pin the cross-process handoff: the extension trades the daemon root
* token for a session-scoped attach token, and only the loopback terminal agent
* accepts that token from a Chrome extension origin.
