Add ROCm 7.2 support and default to it

[chejh-amd]

Closes #472.

comfy install --gpu amd currently defaults to ROCm 6.3, and the ROCmVersion enum stops at 7.1, so there's no way to pull the current ROCm 7.2 PyTorch wheels. PyTorch now ships ROCm 7.2 wheels at https://download.pytorch.org/whl/rocm7.2, so this adds 7.2 to the enum and makes it the default. Follows the same shape as #379 (which added the flag and bumped the default 6.1 → 6.3), including the test updates.

Changes

• constants.py: add v7_2 = "7.2" to ROCmVersion.
• cmdline.py / command/install.py: bump default rocm_version v6_3 → v7_2.
• uv.py: bump rocmPytorchUrl and rocmTorchBackend rocm6.3 → rocm7.2.
• tests/uv/test_uv.py: test_torch_backend_amd now expects the rocm7.2 default backend.
• tests/comfy_cli/test_install_python_resolution.py: add the 7.2 → whl/rocm7.2 case to the parametrized URL test.

Users can still pin an older build with --rocm-version 7.1 (or 6.x).

Why bumping the default is safe for older cards

The ROCm 7.2 wheel is built for a wide arch list, so RDNA2/older cards stay covered, not just RDNA3/4: gfx900, gfx906, gfx908, gfx90a, gfx942, gfx950, gfx1030, gfx1100, gfx1101, gfx1102, gfx1150, gfx1151, gfx1200, gfx1201

Tested

Verified torch 2.12.1+rocm7.2 installs and initializes from the rocm7.2 index on two AMD systems:

GPU	Arch	ROCm	torch	cuda.is_available()
AMD Radeon AI PRO R9700	gfx1201 (RDNA4)	7.2.0	2.12.1+rocm7.2	True
Radeon 8060S / Ryzen AI Max+ 395 (Strix Halo)	gfx1151 (RDNA3.5)	7.2.1	2.12.1+rocm7.2	True

Unit tests pass locally: pytest tests/uv/test_uv.py tests/comfy_cli/test_install_python_resolution.py → 61 passed.

📝 Walkthrough

Walkthrough

The default ROCm version used across comfy-cli was bumped from 6.3 to 7.2. A new ROCmVersion.v7_2 enum member was added, and default parameters plus wheel URLs/backend tags in the CLI, installer, and DependencyCompiler were updated accordingly, with tests adjusted to match.

Changes

ROCm 7.2 default update

Layer / File(s)	Summary
ROCmVersion enum and torch URL comfy_cli/constants.py, comfy_cli/uv.py	Adds ROCmVersion.v7_2 = "7.2" and updates DependencyCompiler.rocmPytorchUrl/rocmTorchBackend from rocm6.3 to rocm7.2.
Default rocm_version wiring comfy_cli/cmdline.py, comfy_cli/command/install.py	Changes default rocm_version from v6_3 to v7_2 for the install CLI option, pip_install_comfyui_dependencies, and execute.
Test expectations for rocm7.2 tests/comfy_cli/test_install_python_resolution.py, tests/uv/test_uv.py	Adds a v7_2 parametrized test case and updates the AMD torch backend assertion to "rocm7.2".

No sequence diagram needed here — just a version number getting its glow-up, from 6.3 to a snazzier 7.2! 🎉

Poem
A rabbit hopped through ROCm's code,
Found 6.3 an outdated road,
With a twitch of nose and a cheerful grin,
Bumped it to 7.2 and let the new torch spin! 🐇⚡
