The Desktop "Approvals: off" toggle persists approvals.mode: off. The shell
guards (check_all_command_guards / execute_code) honour it as a bypass, but
_run_approval_gate, the shared gate that computer_use, plugin approval rules,
SSH-config writes and the dangerous-pattern prompt all route through, only
checked _yolo_active() (process --yolo / session /yolo). So with approvals
off, every destructive computer_use action still prompted.
Regressed when 3e066dfedd moved computer_use onto the shared gate: its old
private gate never consulted mode at all, and the shared gate had never been
given the third bypass source. Gate now mirrors the shell guards:
yolo OR approvals.mode == "off" -> approved. Hardline blocks and deny rules
still run before it.
