Daniel Han 27c81d493b install.ps1: make the release preservation robust across sessions and failures
Three review follow-ups on the Windows port:

- The previous-release probe reads dist metadata rather than importing
  torch, matching install.sh. A broken CUDA/ROCm DLL (or an import slow
  enough to hit the timeout) made the probe return nothing, so the pin
  was never created and the installer replaced the venv with the newest
  supported release even though UNSLOTH_TORCH_UPGRADE was unset.

- The preservation state is reset at the top of the install instead of
  inside the existing-venv branch. Under the documented irm | iex flow
  the script scope IS the caller's session, so a second invocation
  against a different UNSLOTH_STUDIO_HOME with no existing venv skipped
  the branch and inherited the earlier run's release, pinning a fresh
  install to an unrelated venv's torch. The pin is reset with it, so the
  no-index fallback path cannot see a stale pin either.

- UNSLOTH_KEPT_TORCH is cleared from an outer finally around the
  installer entry point. The in-flow clears and Exit-InstallFailure
  cover the handled paths, but a terminating exception between the
  export and the end of setup left the handoff set in a session that
  outlives the installer, where a later studio setup or update would
  consume the abandoned exact pin.

Verified the metadata probe end to end (returns the installed release
through the bounded runner; a missing interpreter still yields null).
Three regression guards added to tests/studio/test_previous_torch_pin.ps1
for the metadata read, the pre-branch reset ordering and the outer
finally. Full sh, ps1 and pytest installer batteries pass (host-defaults
and the tokenizers negative-control are the known pre-existing
failures).
