The issue I ran into was that responses from anthropic compatible
providers, like Kimi for Coding, have no space after `data:`. This
change just adds a quick check to also allow for those providers to
work.
Before it just resolved but did not show any output:

width=50%/>
Now it returns the proper result:

width=50%/>
Normal Anthropic models still work as expected:

/>
Config to test
```json
"language_models": {
"anthropic": {
"api_url": "https://api.kimi.com/coding",
"available_models": [
{
"name": "kimi-for-coding",
"display_name": "Kimi 2.5 Coding",
"max_tokens": 262144,
"max_output_tokens": 32768,
},
],
},
}
```
TLDR:
- Accepts SSE data:{...} lines (no space) emitted by some alternative
Anthropic providers, in addition to the standard data: {...} format.
Release Notes:
- Fixed Anthropic streaming for alternative providers by accepting SSE data:{...} (no space) lines.
