Function extract_attributes_definitions

src/parser/classes.rs:529–553

Extract Eloquent attribute defaults from a class's `$attributes` property. Scans the class members for a `$attributes` property with an array initializer (`protected $attributes = [...]`) and infers PHP types from the literal default values. Returns a list of `(column_name, php_type)` pairs. For example, `'role' => 'user'` produces `("role", "string")` and `'is_active' => true` produces `("is_a
