A Swift port of the libnds hello_world example — a simple console print demo.
It prints a greeting, runs a VBlank-driven frame counter, reads the touch
screen, and exits on START.
This is the smallest example: a single source/main.swift plus a Makefile that pulls in the shared scaffolding in ../common. See the top-level README for how the build and the C shim work.
