docs: request the mlx extra in the documented setup commands (#2245)

Since #2087 moved mlx, mlx-lm, mlx-vlm and mflux out of `dependencies`
into the `mlx` extra, the documented setup path never installs them, and
`[tool.uv]` sets no default extras. `uv run exo` starts the API, then
every runner crashes with `ModuleNotFoundError: No module named 'mlx'`
(#2156).

Adds the extra to the commands documented as the way to set up:

- README macOS: `uv sync --extra mlx`
- README Linux: `uv sync --extra mlx-cpu`, with the mlx-cuda12 /
mlx-cuda13 alternatives
- CONTRIBUTING.md quick start
- `just sync` / `just sync-clean`, which `just build-app` runs before
pyinstaller — the spec aborts when the mlx Metal libraries are missing

Docs plus two justfile recipes; no dependency or lock changes. Backend
choice stays explicit, since mlx-cpu / mlx-cuda12 / mlx-cuda13 /
mlx-none are declared as conflicting extras.

#2234 overlaps on the macOS README block only, via a setup script that
runs `uv sync --extra mlx`; the Linux block, CONTRIBUTING.md and the
justfile are not covered there.
