[Idea] Create a strict list of supported platforms

[lextm]

I think based on reports like #136 it might be reasonable to establish a strict list of supported platforms, so that users of MewUI know clearly what kind of support can be expected.

.NET Releases

Current since MewUI is desktop centric, I think it is good enough to support what is not yet end of life from Microsoft,

https://dotnet.microsoft.com/download/dotnet

• .NET 8/9/10 right now.

If one day mobile support is added #107, then maybe the MAUI lifecycle to be aligned,

https://dotnet.microsoft.com/en-us/platform/support/policy/maui

• .NET 10 right now.

OS Versions

Once the .NET minimal release is determined, the official list from Microsoft can then be reused,

https://github.com/dotnet/core/blob/main/release-notes/8.0/supported-os.md

If users are with an OS that reached end of life (like Windows 7), then that issue can be set with a lower (or even lowest) priority.

Thanks for the suggestion!

I agree with the general direction. Windows 10 is the official baseline, but I still hope MewUI can run in as many environments as reasonably possible.

That said, Windows 7 usage is currently around the 1% range, so I see Windows 7-specific issues as lower priority unless they also affect supported platforms.

I will consider how to document this more clearly, including the difference between officially supported platforms and best-effort environments.
