+    Reset the nRF54L target using OpenOCD before starting broadcast.

+    Looks for interface config files in the project at `src/openocd/` relative to this module only.
+    Accepts filename variants per slot:
+      - slot 0: raspberrypi-swd0.cfg or swd0.cfg
+      - slot 1: raspberrypi-swd1.cfg or swd1.cfg

+          -c "reset run" \
