### ⏯ Playground Link

### 💻 Code

```ts
import ZodRoute from "zod-route-schemas";
import z from "zod";

export const organization = new ZodRoute(
"/org/:organizationId",
z.object({ organizationId: z.number() }),
);
```

### 🙁 Actual behavior

```
> tsc

src/index.ts:4:14 - error TS4094: Property 'parts' of exported anonymous class type may not be private or protected.

4 export const organization = new ZodRoute(
~~~~~~~~~~~~

src/index.ts:4:14 - Add a type annotation to the variable organization.
4 export const organization = new ZodRoute(
~~~~~~~~~~~~

src/index.ts:4:14 - error TS4094: Property 'typeHints' of exported anonymous class type may not be private or protected.

4 export const organization = new ZodRoute(
~~~~~~~~~~~~

src/index.ts:4:14 - Add a type annotation to the variable organization.
4 export const organization = new ZodRoute(
~~~~~~~~~~~~
```

I don't see what the problem is here, because as you can see below, the generated `.d.ts` would have the private field types from the class declaration in `zod-route-schemas`.

### 🙂 Expected behavior

## Outputs the following `.d.ts` like TS5/6:
```ts
import ZodRoute from "zod-route-schemas";
import z from "zod";
export declare const organization: ZodRoute<"/org/:organizationId", z.ZodObject<{
organizationId: z.ZodNumber;
}, "strip", z.ZodTypeAny, {
organizationId: number;
}, {
organizationId: number;
}>, z.ZodType<{
organizationId: number;
}, any, {
organizationId: number;
}>, z.ZodType<{
organizationId: number;
}, any, {
organizationId: number;
}>>;
//# sourceMappingURL=index.d.ts.map
```

### Additional information about the issue

**Doesn't happen with `"module": "preserve"`**, but happens with `"commonjs"`, `"nodenext"`, maybe others

`ZodRoute` declaration in `zod-route-schemas/index.d.ts`:

```ts
declare class ZodRoute, FormatSchema extends InvertSchema = InvertSchema, PartialFormatSchema extends PartialSchema = PartialSchema> {
readonly pattern: Pattern;
readonly schema: Schema;
private parts;
readonly formatSchema: FormatSchema;
readonly partialFormatSchema: PartialFormatSchema;
readonly exact: boolean;
private typeHints?;
```
