Misleading startup message about “Torch version too old”

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have searched existing issues to make sure this isn't a duplicate
- [x] I have tested with all custom nodes disabled ([see how](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled))

### What happened?

## Description
During ComfyUI startup, the console displays a warning indicating that the Torch version is “too old,” even when the bundled PyTorch package is fully up-to-date.
In my case, ComfyUI reports:

`PyTorch version: 2.5.1+cu124`

This is one of the latest official builds, but the warning still appears.
This makes the message misleading and suggests that the user's installation is outdated or incompatible, even when it is not.

## Expected behavior
The startup check should correctly validate the actual installed Torch version and only warn users when their PyTorch version truly falls below the minimum supported version.
Alternatively, the message should be updated to reflect what condition is actually being detected (e.g., missing features, incompatible extensions, etc.).

## Actual behavior
A generic warning is shown claiming that the Torch version is “too old,” even when using up-to-date PyTorch builds bundled with ComfyUI portable.

## Impact

- Causes confusion for users.
- Suggests unnecessary reinstallations or troubleshooting.
- Makes debugging more difficult when the message does not reflect a real problem.

## Suggested fix

Update the version check logic to correctly evaluate the installed Torch version.
Or update the startup message to clarify what specific feature or version requirement triggered the warning.
Optionally print the detected Torch version alongside the requirement for easier comparison.

## Environment

- ComfyUI portable for Windows
- PyTorch: 2.5.1+cu124
- GPU: NVIDIA RTX 3060 Ti
- Windows 10
