Annotation Interface OneToMany

@Target({FIELD,METHOD}) @Retention(RUNTIME) public @interface OneToMany
Annotation that establishes a one-to-many relationship between two entities in the context of Object-Relational Mapping (ORM). This relationship maps a collection of child entities to a parent entity.

The `mappedByField` attribute specifies the field in the child entity that owns the relationship. It is essential to correctly define this attribute to maintain bidirectional associations between parent and child entities.

Attributes: - `mappedByField`: Declares the name of the field in the child entity that acts as the owner of the relationship.

This annotation is primarily applied to fields or methods in an entity class to indicate the one-to-many association. Litebridge leverages this metadata to manage cascading operations and other relational operations.

Example Use Case: - A `Department` entity can have a one-to-many relationship with `Employee` entities, where the `mappedByField` specifies the field in the `Employee` entity referencing the `Department`.
