`computer_use` carried two Bot Screen actions, `request_handoff` and `wait_for_human`, that let the model ask for the screen and then block a tool call until the human handed it back. Both only make sense when a person is guaranteed to be watching the Desktop pane; from Telegram, the CLI or a cron worker the request lands nowhere and the wait burns minutes before returning. The blocking wait also fought the sequential tool deadline (600 s default vs 420 s), so the model saw a timeout before the wait returned while the thread stayed parked. The agent now simply says what it needs in its reply and ends the turn; the user takes over from the pane, does the step, hands back and tells it to continue. Take over / hand back and every fence (actions refused with human_has_control, epoch-voided results, suppressed thumbnails) are unchanged. Removes the handoff module, the schema entries and their host-conditional rewriter, the lease's pending_handoff field and wait helpers, and the "Bot needs you" badge in the pane.
