@DeepFreeze

Recursively freeze instances at construction so nested objects and arrays cannot be mutated.

Kind	Runtime class
Backends	legacy, stage3
Requires generate	No

Example

import { DeepFreeze } from 'lombok-typescript/legacy';

@DeepFreeze
class AppConfig {
  db = { host: 'localhost', port: 5432 };
  features = ['auth', 'billing'];
}

const cfg = new AppConfig();
cfg.db.host = 'other'; // throws in strict mode (frozen object)

Plain objects and arrays on the instance are frozen recursively. Non-plain values (e.g. Date) are left as-is. Circular references are handled safely via a WeakSet visit tracker.
