v2.0.3 - faster startup + update fix

Faster startup + accurate update checker.

What changed

• Cold start cut from ~5.4 s to ~0.5 s. The 3 PerformanceCounter constructors used by MemoryMonitorService were blocking the UI thread for ~4.8 s during DI resolution. They now build lazily on the monitor loop thread, and the main window shows before ViewModel.InitializeAsync runs.
• Update checker no longer fires false positives. ParseVersion(v2.0.2) returned Version(2,0,2) with Revision=-1, which compared as less than the matching assembly version 2,0,2,0, so the app reported a phantom new version. Normalised. Also added a default <Version>2.0.3</Version> to the csproj so dev/CI builds no longer report themselves as 1.0.0.0.
• README screenshot refreshed to show the new lime/card UI.
• .editorconfig added for consistent formatting across editors.
