Autofix S101

code: `assert x != 0`
ruff: 0.0.291
command: `ruff check --fix --fixable S101 .`
error: `S101 Use of `assert` detected`

This is an easy fix to substitute in the code specially when opted-in by the developer (if not automatically)

Start by reproducing the provided `assert x != 0` snippet with `ruff check --fix --fixable S101 .` using Ruff 0.0.291. Determine what safe autofix behavior is intended when developers opt in, and verify the resulting command output against the issue's stated S101 diagnostic; the issue does not name implementation files or tests.
