[Bug]: @microsoft/teams.graph-endpoints typings file size causes high memory usage

Nobody has claimed this yet.

### Bug Description

`@microsoft/teams.graph-endpoints` includes a lot of typings files, including the 25MB dist/types/types.d.ts`. The size and structure of this project causes tsc and tsgo to use significant memory even for very basic projects

### Steps to Reproduce

Have a project with a single file such as:

```ts
import { chats, teams } from "@microsoft/teams.graph-endpoints";

export const req = chats.get({ "chat-id": "example-chat-id" });
export const t = teams;
```

https://github.com/mjbvz/test-ts-teams-project provides a complete an example

### Expected Behavior

Normal TSServer / tsgo memory usage

### Actual Behavior

The import causes an extra 300MB memory usage for tsgo and extra 500MB for tsserver

### SDK Version

2.0.13

### Node.js Version

22.14.0

### Additional Context

Also opening an issue against TypeScript to investigate this but a 25MB d.ts also seems pretty high

Start with the import in the provided test-ts-teams-project reproduction and inspect the 25MB dist/types/types.d.ts file in @microsoft/teams.graph-endpoints. Run the example with tsc and tsgo to establish the reported memory increase. Done means the package no longer causes the reported excessive memory usage while preserving the typings used by the example.
