11/// Derive macro to generate `fletch_orm::Entity` trait implementation.
12///
13/// # Struct Attributes
14///
15/// - `#[fletch(table = "table_name")]`: Override the table name
16///   (default: `snake_case` pluralized struct name).
17///
18/// # Field Attributes
19///
20/// - `#[fletch(id)]`: Mark the primary key field (required, exactly one).
21/// - `#[fletch(skip)]`: Exclude a field from persistence.
22/// - `#[fletch(rename = "col_name")]`: Override the column name.
23///
24/// # Example
25///
26/// ```ignore
27/// #[derive(Entity)]
28/// #[fletch(table = "users")]
29/// pub struct User {
30///     #[fletch(id)]
31///     pub id: i64,
32///     pub name: String,
33///     #[fletch(skip)]
34///     pub cached_display: String,
35/// }
36/// ```
