Debian versions must start with a digit. When called via 'make deb',
VERSION is passed from Makefile (git describe output includes 'v' prefix).
The strip was previously only done inside the auto-detection branch,
so 'make deb' produced invalid versions like 'v2026.07.30-2-g05604a8-1'.
Now VERSION= runs after the version is determined, regardless
of whether it came from an argument or auto-detection.
