fn launcher_exe_env() -> Vec<(&'static str, OsString)>Expand description
AGENTMUX_LAUNCHER_EXE for the host: this launcher’s own executable, so
the host can invoke launcher CLI verbs (--autostart-status,
--enable-autostart, --disable-autostart) on the user’s behalf. Empty
when current_exe fails — the host then reports auto-start as unavailable.
