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 from the
generated ModelEx struct, which triggers clippy::derive_partial_eq_without_eq
when -D warnings or clippy::nursery is enabled. Eq is a trivial marker
trait that is always valid when PartialEq is present, so passing it
through instead of skipping it is safe and correct.

Fixes #3172.
