30/// Define chainable Eloquent-style local scopes on a model's query builder.
31///
32/// Mirrors Laravel's `scopeActive($query)` / `scopePublished($query)` pattern.
33/// Generates a user-named trait and an `impl` for `QueryBuilder<Model>` so
34/// scopes chain directly: `User::query().active().verified().get(pool)`.
35///
36/// ## Usage
37///
38/// ```ignore
39/// use anvilforge::cast::scopes;
40///
41/// scopes!(UserScopes for User {
42///     fn active(q) -> q.where_eq(User::columns().active(), true);
43///     fn verified(q) -> q.where_not_null(User::columns().email_verified_at());
44///     fn older_than(q, days: i32) -> q.where_lt(User::columns().created_at(), cutoff(days));
45/// });
46///
47/// // In handler code:
48/// use crate::app::Models::UserScopes;
49/// let active_verified = User::query().active().verified().get(pool).await?;
50/// ```
