Rename PyPI distribution from mobius-ai to mobius-onnx (#437)

## Summary

The project was renamed, so this updates the **PyPI/distribution name**
from `mobius-ai` to `mobius-onnx`.

Only the distribution name changes:
- The **import package stays `mobius`** (`import mobius`, the `mobius`
console script, and internal imports are all unchanged).
- The dynamic version still resolves from `mobius.__version__`
(`[tool.setuptools.dynamic]`).

## Changes

- `pyproject.toml`: `name = "mobius-onnx"`
- Updated every user-facing `pip install mobius-ai[...]` reference →
`mobius-onnx[...]` across docs, examples, tests, and the CHANGELOG.
- `src/mobius/__main__.py`: GGUF install hint in `mobius build-gguf`.
- `examples/model_builder_comparison.py`:
`importlib.metadata.version("mobius-onnx")`.

30 files changed, 33 insertions(+), 33 deletions(-). Ruff clean.

## Follow-up (out of scope for this PR)

The `mobius-onnx` name must be claimed/registered on PyPI and the
publish workflow's credentials/name updated before the next release.
