/**
 * Lower instance class field initializers into constructor assignments.
 *
 * When `useDefineForClassFields` is `false` (the standard Angular tsconfig),
 * field initializers must run as assignments inside the constructor body
 * rather than as native ES class field initializers. This ensures:
 *
 * 1. `inject()` calls in fields have an active injection context
 * 2. Fields referencing other injected fields work (sequential assignment)
 * 3. Constructor parameter properties are available to field initializers
 * 4. Inheritance works (parent constructor runs before child field assignments)
 *
 * Rules:
 * - Regular fields with initializers: remove declaration, add `this.field = value;`
 * - Private fields (`#field`) with initializers: keep `#field;` declaration, add `this.#field = value;`
 * - Static fields: not lowered
 * - Fields without initializers: not lowered
 * - `declare` fields: not lowered
 * - Assignments are inserted after `super()` (if present), before existing constructor body
 * - If no constructor exists, one is created (with `super(...args)` for subclasses)
