This reverts commit 7aea5256b1.
* fix windows sysconfig.get_config_var("MULTIARCH") is None
* fix correct indentation in UOp pretty_print for repeated references
When a UOp was referenced multiple times, the walrus operator notation
(e.g., x0:=) was correctly used for the first occurrence, but subsequent
references had misaligned indentation due to an extra space character.
Fix indentation misalignment in pretty_print() when UOps are referenced
multiple times.
* add simple unit tests for UOp repr

`UOp.render()` crashed with `IndexError: tuple index out of range` when
the UOp graph contained a `VECTORIZE` with empty `src=()`. This occurs
when reshaping to scalar shape `()`, e.g., `Tensor.ones(4).sum()`.
The bug was in the renderer's VECTORIZE pattern: `all_same(())` returns
`True` (vacuous truth), causing the code to access `x.src[0]` on an
empty tuple.
- Fix `IndexError` when calling `UOp.render()` on graphs containing
empty `VECTORIZE` nodes.
- Add test for empty `VECTORIZE` rendering.
