## Message

```
Fix error when Copilot calls tools without arguments (#30371)

Fixes https://github.com/zed-industries/zed/issues/30346

The model can output an empty string to indicate the absence of
arguments, which can't be parsed as a `serde_json::Value`. When that
happens, we now create an empty object instead on behalf of the model.

Release Notes:

- Fixed a bug that prevented Copilot models from calling the
`diagnostic` tool.
```
