error: EOF while parsing an object

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 15.7.4 (24G517)

### Expected behaviour

I don't expect Kiro to encounter unrecoverable errors when writing source files.

### Actual behaviour

Kiro repeatedly runs in to this error when trying to write a particular source file:

```
Kiro is having trouble responding right now:
0: Failed to receive the next message: request_id: 79743423-0033-4872-bff4-a24131b0280d, error: EOF while parsing an object at line 1 column 84

Location:
crates/chat-cli/src/cli/chat/mod.rs:1524

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.
```

It doesn't seem to be consistent for every source file, but for the particular workflow I'm trying to run it hits it every time.

### Steps to reproduce

I don't know how to reproduce this in general, but it is reliably reproduced in my project.
