Subject: [PATCH] fix: pass through Eq derive in ModelEx to satisfy
 clippy::derive_partial_eq_without_eq

The model_ex macro was silently stripping the Eq derive, causing
clippy::derive_partial_eq_without_eq when -D warnings or nursery is
enabled. Eq is a marker trait; users who write #[derive(Eq)] opt in.
If their model has f64/f32 fields, the compiler errors as expected.

Fixes #3172.
