The in-distro cleanup probed a hardcoded candidate set ('', Ubuntu,
Ubuntu-24.04, Ubuntu-22.04, Debian) on every Windows uninstall, wiping
/root/.unsloth in any reachable distro even when the WoA fallback never
ran -- on an x86 AMD box this deletes a ROCm-on-WSL Studio the AMD flow
installed. Use the evidence the installer already records: clean only
the wsl-distro.txt marker distro or UNSLOTH_WSL_DISTRO; keep the broad
candidate probe solely for legacy marker-less installs, which can only
exist on ARM64 hosts.
Addresses the open Codex P1 on this path. Verified gating matrix:
x86+no-marker -> no cleanup; marker/env -> that distro only;
ARM64+no-marker -> legacy broad probe unchanged.
