7/// Главный derive-макрос. Генерирует:
8/// - `impl Model for T`
9/// - `struct NewT { ... }` (без PK и auto-полей)
10/// - Методы `find`, `create`, `save`, `delete`, `all`, `query`, ...
11/// - Структуру `TColumns` для DSL-фильтров
12/// - `impl HasColumns for T`
13///
14/// # Пример
15/// ```rust
16/// #[derive(Model, Debug, Clone, Serialize, Deserialize)]
17/// #[orm(table = "users")]
18/// pub struct User {
19///     #[orm(primary_key, auto_increment)]
20///     pub id: i64,
21///
22///     #[orm(unique, index)]
23///     pub email: Email,

25///     pub username: String,
26///
27///     #[orm(default = true)]
