Generated code has unexpected "reference-tracker"

## Problem

The generated code has unexpected "reference-tracker" flags. ie see the code below

```ts
const paramet0 reference-tracker>erName =
```

## Steps to reproduce the issue

In chat mode, ask to generate typescript CDK code using Sonnet 3.7.
But that's just an example prompt, that happens on all generated code

## Expected behavior

Like a few days ago, having clean generated code

## System details (run `AWS: About` and/or `Amazon Q: About`)

```
OS: Darwin arm64 24.5.0
Visual Studio Code extension host: 1.101.2
Amazon Q: 1.82.0
node: 22.15.1
electron: 35.5.1
```

Reproduce the issue in Amazon Q chat mode by requesting TypeScript CDK code with Sonnet 3.7, then inspect the generated output for the unexpected "reference-tracker" text. Done means generated code is clean and no longer contains those flags across the reported reproduction prompts.
