`expect` on struct does not cover the derives

Minimal reproducer:

#[expect(clippy::derived_hash_with_manual_eq)]
#[derive(Hash)]
pub struct Thing;

impl PartialEq<Thing> for Thing {
    fn eq(&self, _other: &Thing) -> bool {
        true
    }
}

I ran cargo clippy, and I expected the expect to suppress the clippy::derived_hash_with_manual_eq lint. Instead, I got the following:

error: you are deriving `Hash` but have implemented `PartialEq` explicitly
 --> src/lib.rs:2:10

2 | #[derive(Hash)]
  |          ^^^^

note: `PartialEq` implemented here

5 | impl PartialEq<Thing> for Thing {
  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#derived_hash_with_manual_eq
  = note: `#[deny(clippy::derived_hash_with_manual_eq)]` on by default
  = note: this error originates in the derive macro `Hash` (in Nightly builds, run with -Z macro-backtrace for more info)

warning: this lint expectation is unfulfilled
 --> src/lib.rs:1:10

1 | #[expect(clippy::derived_hash_with_manual_eq)]
  |          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  |
  = note: `#[warn(unfulfilled_lint_expectations)]` on by default

I haven't found any way to apply the expect to the derive except by putting it on the containing module.

Note, however, that replacing the expect with an allow does successfully suppress the warning. This seems particularly surprising, and violates the expectation that replacing an allow with an expect should always work.

Reproduce the issue from the minimal example in src/lib.rs by running cargo clippy, comparing #[expect] with #[allow] on the Hash derive. Trace how the derived_hash_with_manual_eq lint and the derive macro handle expectations; done means #[expect] suppresses the lint without producing an unfulfilled_lint_expectations warning.
