install.ps1/uninstall.ps1: add UNSLOTH_INSTALL_REF + fix WSL symlink uninstall hole

Browse source 
install.ps1: fetch repo-versioned WSL-fallback assets (provision_llama_cuda.sh,
unsloth.ico) from a configurable git ref via new UNSLOTH_INSTALL_REF env var
(defaults to main, so existing users are byte-for-byte unaffected). Lets the
ARM64+NVIDIA WSL-fallback GPU path be exercised end-to-end on a branch before it
merges (provision_llama_cuda.sh does not exist on main until then).

uninstall.ps1: the WSL cleanup rm -rf'd /root/.unsloth but left the
~/.local/bin/unsloth launcher symlink dangling, so `unsloth` still resolved on
PATH after an uninstall. Also remove /root/.local/bin/unsloth and
/home/*/.local/bin/unsloth.
