Enable auto-execution on USB attack modules for aggressive exploitation

- HID Inject: auto-triggers payload injection on host detection
- USB Gadget: auto-detects best device class and enumerates immediately
- JTAG USB Bridge: auto-detects protocol and starts bridging on entry
- RNDIS Bridge: auto-starts ethernet gadget and DHCP server on entry
- USB Sniffer: auto-captures packets immediately on entry

All USB modules now auto-execute without manual trigger, enabling plug-and-exploit workflow.
