The delete was approved. The path was wrong.

## Resolve and check every delete target
- Before any recursive delete or "clear" (`rm -r`, `rmdir /s`, `Remove-Item -Recurse`, `venv --clear`,
  `git clean`, `shutil.rmtree`), resolve the target to an absolute path and print it.
- Refuse if the target is empty, `/`, a drive root, `~`/home, the current working directory, the repo
  root, or any parent of the repo. Use `${VAR:?}` in shell so an empty variable aborts.
- Delete only inside an allowlist of disposable locations (a `mktemp -d` dir or a named build output).
  Never write guards as "anything outside X is allowed".
- Test destructive code with a temp directory or an injected delete function, never a real path.
- If a command fails with "No such file or directory" right after a delete, stop everything and tell the user.
