Instead of hard-failing when AVX is not present, detect whether the host
CPU supports AVX + AVX2 + MOVBE (x86-64-v3 microarchitecture level) and
select the appropriate upstream binary accordingly:
- iSponsorBlockTV-x86_64-linux → modern CPUs (AVX/AVX2/MOVBE)
- iSponsorBlockTV-x86_64-linux-v1 → any x86_64 CPU (fallback)
The same detection logic is applied in update_script() so updates
stay consistent with the initially installed binary type.
