Update to nightly-2025-08-04.

- `tcx.get_attrs_unchecked(...)` was replaced with
  `tcx.get_all_attrs(...)`.
- `run_link` has been removed.
- `BuilderMethods::tail_call` was added. It's currently `todo!()`.
- Adjust expected test outputs for very minor error message formatting
  changes.
- And update to glam 0.30.8.
