fix(classes.doc): Avoid emitting instance fields for collection and manager to preserve decorator-defined prototype getters

 3. `Symbol.metadata` on constructors is read-only (managed by runtime)
 4. Field decorators run before class decorators (guaranteed order)

+## ES2022 Class Fields & Prototype Getters - Fixed in v7.0.15
+
+### Issue
+ES2022 class fields (`useDefineForClassFields: true`) create own properties during construction that shadow prototype getters defined by decorators.
+
+### Solution
+Use `declare` keyword for instance properties that are accessed via prototype getters:
+```typescript
+// In SmartDataDbDoc (ts/classes.doc.ts):
+declare public collection: SmartdataCollection<any>;  // Type-only, no JS emitted
+declare public manager: TManager;  // Type-only, no JS emitted
+```
+
+### Key Insight
+- `declare` tells TypeScript this is a type-only declaration
+- No JavaScript code is emitted for `declare` properties
+- Prototype getters defined by `@Collection` and `@managed` decorators are no longer shadowed
