feat: ollama full support for golem and wasm

[Rutik7066]

Adds Ollama Support

• We can use Ollama both locally and remotely by setting the environment variable GOLEAM_OLLAMA_BASE_URL with the -e flag.
• Users can specify a local path or a URL for the image.
• We send and stream the full received response by relaying the remaining data in provider_metadata_json, which is highly beneficial for consumers.
• We support all model options provided by Ollama, allowing consumers to have fine-grained control over their models.
• We have introduced the common StreamError and a common Stream interface that is identical to the existing EventStream. This is extended by EventStream and NdJsonStream, and we can easily add more streaming formats while ensuring minimal code changes, better code maintainability, and adherence to best practices.

@Rutik7066 Others are ahead of you by a significant amount, I will close this, but feel free to re-open if you address all of these issues and follow instructions precisely. Thanks!

[Rutik7066]

@jdegoes could you please open this PR I am working on this. I will update the lastest change I have implemented ndjson alongside eventsource.

[Rutik7066]

All tests are successful. I will add CI test and record video ASAP

@mschuwalow PR is ready for 🚀

Looks good to me, aside the few minor comments. I like how you handled the ndjson and sse stream differences.

[mschuwalow]

As Stream is already a commonly used trait, I would prefer a name that causes less collision

@mschuwalow added the changes and ci fixes as well. CI run link https://github.com/Rutik7066/golem-llm/actions/runs/15250412169/job/42886202542

Yes, with this implementation it would be easier to add different types of stream and will be more maintainable.
