nx_nishios_kbd.nx -- NishiOS GUI rung-5: LIVE KEYBOARD INPUT + a real shell line editor. Turns the terminal from a `cat` into something you TYPE into. Models the PS/2 keyboard path a kernel actually walks: read scancodes from the controller (port 0x60), translate set-1 make codes -> ASCII via a keymap, handle BACKSPACE line-editing, echo, and on ENTER dispatch a shell builtin. The demo types 'v','e','e',<backspace>,'r',<enter> -> the line editor yields "ver" (the stray 'e' erased), the shell runs it -> "NishiOS 0.1 sovereign", and the terminal renders prompt+command+output. KAT: the line editor produced "ver" (backspace worked), the shell dispatched the right output, both the command line and the output render, and the BMP exports. HONEST SEAM: the scancode SOURCE is scripted (no live PS/2 controller modeled on the emu -- that IRQ1 wiring is the hardware rung); the driver LOGIC (port read, set-1 keymap, line edit, echo, dispatch) is real. No hw writes (Rule 26). expect_exit: 0 license_tier: ORIGINAL
