[BUG] Store is unsusable if "Store." is in a comment line.

This produce no error, but the reactivity of the store does not work anymore:

```ts
/**
* Store.
*/
class MyStore extends Store {
```

This is ok:

```ts
/**
* Store
* ^ without dot it is ok
*/
class MyStore extends Store {
```

version: 1.4.0

Reproduce the issue with the TypeScript snippet showing `Store.` inside a comment, then trace the compile-time Store handling and reactivity entry point. Compare it with the version without the dot and verify that comments no longer disable store reactivity in version 1.4.0.
