feat(iso): append auto-incrementing _RCn suffix to ISO filenames

Browse Source 
Rebuilds of the same version overwrote the previous ISO under an
identical filename, making a flashed stick indistinguishable from a
newer build. The builder now keeps a per-version RC counter (next to
the build counter) and names outputs like
archipelago-installer-1.7.101-alpha-unbundled-x86_64_RC2.iso.
Override with RC=n env when re-cutting a specific candidate.
