Add 5 USB attack modules: HID injection, gadget emulation, JTAG bridge, RNDIS, sniffer

- HID Inject: USB keyboard/mouse emulation with configurable payloads and 50ms inter-key delays - USB Gadget: Emulate mass storage, CDC/ACM, HID composite, RNDIS, MTP device classes to bypass host filters - JTAG USB Bridge: Tunnel JTAG/SWD debug port over USB for OpenOCD/GDB-compatible debugging - RNDIS Bridge: Virtual ethernet over USB with DHCP server at 192.168.7.1 for host network pivoting - USB Sniffer: Monitor and log USB traffic from connected devices with filtering and hex payload capture Brings toolkit to 30 total modules organized into 7 categories. All USB modules are manual-trigger only.
