## What changed
- Move the lint to `nightly-2026-08-20` and Dylint `6.1.0`, updating CI, release artifacts, Bazel configuration, and installation instructions.
- Adapt to the updated rustc and Clippy APIs, including resolving `Option::None` through type aliases when checking for uncommented arguments.
- Set the `chatgpt` crate's `recursion_limit` to `256`.
## Testing
Extend the UI fixture to expect an uncommented-argument warning for `OptionalString::None`, where `OptionalString` aliases `Option<String>`.
