研究方向

The issue requests a new Clippy lint that detects #[allow(warnings)] and emits a warning that cannot be silenced. To implement, one should study how existing lints are defined in Clippy (e.g., in clippy lints/src/) and understand lint attribute handling. The lint should check for the allow(warnings) attribute on items and report a warning with a level that is not suppressible, perhaps using a custom lint level. The challenge is ensuring the lint itself is not disabled by the same attribute. Look into Clippy's lint registration and the Rust compiler's lint infrastructure.
