Add setup.sh to facilitate bootstrap on portable

[idlesign]

Hi,

I'd like to propose a helper script that saves time bootstrapping portable version on Linux.

All setup can be as easy as

./setup.sh --manager --torch=nvidia --torch-nightly

It's also easy to maintain and update default torch versions.
Yet the script requires uv to be installed.

I've just added a small hint in the README, but it seems that other instructions in that could be also simplified further.

Looking forward for any feedback.

📝 Walkthrough

Walkthrough

This pull request introduces automated environment setup tooling. A new setup.sh script handles virtual environment creation, dependency installation, and flexible PyTorch installation with support for multiple vendors (AMD, Intel, NVIDIA) and nightly builds. Accompanying README.md documentation provides usage examples and notes the uv dependency requirement. The changes are purely additive with no modifications to existing code.

223-232: Good documentation addition.

Clear and helpful section that introduces the setup helper script with a practical example.

Minor note: Line 228 uses ; as a comment prefix, which is unconventional in shell (typically # is used). While ; at line start is technically valid bash (empty command), using # would be more idiomatic.

📝 Minor style suggestion

 ```shell
-; install ComfyUI & Manager dependencies + nightly PyTorch build for Nvidia
+# install ComfyUI & Manager dependencies + nightly PyTorch build for Nvidia
 ./setup.sh --manager --torch=nvidia --torch-nightly

`37-45`: **Consider warning on unknown arguments.**

Unknown arguments are silently ignored (line 43). This could mask user typos such as `--manger` instead of `--manager`, leading to unexpected behavior without feedback.

Also, the `shift` statements inside the case branches have no effect since the `for` loop iterates over a snapshot of `"$@"` and doesn't rely on positional parameter shifting.

In `@setup.sh`:
- Around line 47-58: The install sequence in setup.sh causes torch packages in
requirements.txt to be downloaded twice when the --torch path is used; modify
the script so that when the --torch flag is set you either (a) remove/filter
torch, torchvision, torchaudio entries from the pip install of
requirements.txt/manager_requirements.txt (the uv pip install -r
requirements.txt and uv pip install -r manager_requirements.txt calls) before
that step, or (b) install the vendor-specific torch packages first and then
install requirements.txt with a filtered/--no-deps or a temporary requirements
file to exclude torch entries; update the logic around the uv pip install calls
and the --torch handling to ensure torch is only downloaded/installed once and
keep MANAGER branch behavior consistent.
