v1.1.2 - Fix hardcoded version string in print_version() - use VERSION define from main.h

The print_version() function was displaying a hardcoded 'v1.0.0' string instead
of using the VERSION define from main.h. This caused version mismatches where
the git tag and main.h showed v1.1.1 but the binary reported v1.0.0.

Now print_version() uses the VERSION macro, ensuring all version displays are
consistent and automatically updated when increment_and_push.sh updates main.h.
