Pin unsloth-zoo>=2026.6.5 in install scripts (#6440)

Browse source 
The base-install lines passed a bare unsloth-zoo spec and relied on the
co-installed unsloth>=2026.6.7 (whose pyproject pins unsloth_zoo>=2026.6.5)
to floor unsloth-zoo transitively. Make the floor explicit so the install
scripts stay in sync with pyproject and the bare spec can never resolve below
the version that ships unsloth_zoo.diffusion_studio (the DiffusionGemma Studio
runner), first released in unsloth-zoo 2026.6.4. Leaves the reinstall/upgrade
flags and the git-main overlay untouched.
