Bug: torchvision as a hard dependency breaks install on Intel Mac (x86_64)

[ssarmin]

Describe the bug

torchvision>=0.25.0 is listed as a required (non-optional) dependency in pyproject.toml, which pulls in torch 2.10–2.12. Neither torch nor torchvision publish wheels for macosx_*_x86_64 at those versions.

As a result, fenn cannot be installed at all on Intel Macs, even by users who only want the CLI or dashboard and never touch the torch-based trainers.

How to reproduce

uv sync --group dev

Expected behavior

uv sync should succeed on Intel Macs, at least for users not opting into vision/torch features.

Observed behavior

error: Distribution `torch==2.12.1 @ registry+https://pypi.org/simple` can't be installed because it doesn't have
       a source distribution or wheel for the current platform

hint: You're on macOS (`macosx_26_0_x86_64`), but `torch` (v2.12.1) only has wheels for the following platforms: `manylinux_2_28_aarch64`, `manylinux_2_28_x86_64`, `macosx_14_0_arm64`, `win_amd64`; consider adding "sys_platform == 'darwin' and platform_machine == 'x86_64'" to `tool.uv.required-environments` to ensure uv resolves to a version with compatible wheels

Environment

• OS: macOS 26.6.2 (build 25G83), Intel (x86_64)
• Python version: project requires >=3.11 (per pyproject.toml); uv resolves/manages this itself — system python3 is 3.9.6 and isn't what's used
• Package version: fenn v0.2.4; failing dependency is torchvision>=0.25.0, resolving to torch==2.12.1
• Installation method: uv sync (uv 0.11.29, x86_64-apple-darwin)

Hi @blkdmr, I can propose a change to pyproject.toml to resolve this if @ssarmin doesn't have one in mind already. Let me know 🙂.

@hendo-21, Thank you for checking with me.

I think only moving torchvision>=0.25.0 out of the dependencies would be enough. The existing vision/torch dependency-groups already declare torch/torchvision for anyone who needs them, so no additions are needed there.

Does that sound good to you?

I will open a PR shortly.
