Struct AntigravityCanaryLauncher 

pub struct AntigravityCanaryLauncher {
    pub workdir: PathBuf,
}

The Antigravity delivery canary (round-3 B2/D-07): one throwaway agy turn over the SAME bidirectional stream-json transport a production Antigravity stage uses, with the agent-aware first turn (monitor::user_turn_line_for) and close rule (CloseRule::for_agent). The trust decision stays in run_delivery_canary, which now resolves it agent-aware via agent_result::token_reported_in_capture_for.

Fields

workdir: PathBuf

Working directory for the throwaway child — same rationale as ClaudeCanaryLauncher::workdir.
