Add robopi-hw-test, which watches the GPIO1_D5 button (gpiochip1/29) and drives GPIO1_B0 (gpiochip1/8) and GPIO0_C2 (gpiochip0/18) high on each press. Outputs latch high by default; --toggle flips them per press. - src/hw_test.c: new program (mirrors sig_led_key.c gpioevent polling). - etc/systemd/system/robopi-hw-test.service: new unit, WantedBy=multi-user.target. - Makefile: build, install the binary, /usr/bin symlink, and unit. - debian/postinst: enable and start the service on install.

Summary
Adds a boot-enabled hardware test service for verifying GPIO routing on the RoboPi2 board.
When the GPIO1_D5 button (GPIO61) is pressed, the service drives two output lines high:
/dev/gpiochip1offset 8/dev/gpiochip0offset 18Changes
src/hw_test.c— newrobopi-hw-testprogram. Polls the button rising edge (30 ms debounce) via thelinux/gpio.hgpioevent API, then sets both outputs high. Outputs latch high by default; a--toggleflag flips them on each press. Modeled on the existingsig_led_key.c.etc/systemd/system/robopi-hw-test.service— new unit,WantedBy=multi-user.targetfor boot auto-start.Makefile— builds the binary, installs it under/opt/roboparty/binwith a/usr/binsymlink, and installs the unit.debian/postinst—systemctl enable+startthe service on install.Notes
