-->
This PR adds a **Multi‑Model Prompt Processor** capable of calling OpenAI,
Anthropic and Ollama/Llama models from StreamPipes pipelines.
* **New processor module:** `streampipes‑processors‑llm‑jvm`
* Supports stateless, windowed (N‑turn) or full‑history conversations.
* Exposes a *temperature* slider and validates provider‑specific
credentials.
* Automatically appends the model’s reply as a new event field.
Samples Prompts:
- For a windowed conversation -> `For each input number, calculate and
return the current average. Do not output any other information other than the
answer.`
- For a stateless conversation -> `If the input number is greater than 100,
return "WARNING". Otherwise return "OK"`.
### Remarks
<!--
Is there anything left we need to pay attention on?
Are there some references that might be important? E.g. links to Confluence,
or discussions
on the mailing list or GitHub.
-->
* New third‑party library: **LangChain4j** –
https://github.com/langchain4j/langchain4j (Apache‑2.0). It pulls only
lightweight, provider‑specific HTTP clients.
PR introduces (a) breaking change(s): no
PR introduces (a) deprecation(s): no
### Questions
1. Is it acceptable to ship this as a dedicated*
**`streampipes‑processors‑llm‑jvm`** *artifact, or should it live under*
**`streampipes‑processors‑enricher‑jvm`** *instead?*
2. If a separate artifact is preferred, which distro flavours should include
it?* (i.e. `AllExtensionsInit` (default), `AllExtensionsIIoTInit`,
`ExtensionsIIoTMinimalInit`)?
