V3 support for many tasks as possible in Huggingface, starting with "text-to-image"

With V2, the `HuggingFace` class allowed to do inference on many different models performing different tasks. Moving to V3 many of the available tasks are not functional anymore.

I would like to see them working again with the V3 `ModelBuilder` interface, and to be able to use a short code snippet to deploy a model.
Here's the complete list of the tasks we used to support:
```
"text-classification",
"token-classification",
"table-question-answering",
"question-answering",
"zero-shot-classification",
"translation",
"summarization",
"feature-extraction",
"text-generation",
"fill-mask",
"sentence-similarity",
"automatic-speech-recognition",
"text-to-image",
"text-to-speech",
"audio-to-audio",
"audio-classification",
"image-classification",
"object-detection",
"image-segmentation"
```

The most important tasks for us are "text-generation" (already working on V3) and "text-to-image" (currently broken). If you think you can make at least these two work it would be great.

An example of model that we would like to test is **black-forest-labs/FLUX.2-dev**.

ファイルやテストは指定されていません。まず、すでに text-generation をサポートしている V3 ModelBuilder のパスを読み、その後、提供された FLUX.2-dev モデルを text-to-image 用にデプロイする方法を調査してください。少なくとも text-generation と text-to-image が短いデプロイメントスニペット付きで V3 経由で動作し、列挙されたタスクへのより広範な対応についても可能な範囲で取り組まれていれば完了です。
