Retargets RioJoy.Core/Overlay/Tray + tests from net8.0-windows to net48 so the app can be tested as a framework-dependent build (relies on the in-box .NET Framework 4.8 on Windows 10/11). Builds clean; all 241 tests pass. Polyfills (no behavior change): - PolySharp source generator for init/records/Index/Range/required members. - System.Memory, System.Text.Json, Microsoft.Bcl.HashCode, System.Threading.Channels (tests) NuGet packages. - Compat/Net48Polyfills.cs: GetValueOrDefault, KeyValuePair.Deconstruct, Math.Clamp; tests/TestPolyfills.cs: Task.WaitAsync. Source adjustments for APIs absent on net48: - ArgumentNullException/ArgumentException.ThrowIf* inlined to manual guards. - Convert.ToHexString, Encoding.Latin1, Environment.ProcessPath, ApplicationConfiguration.Initialize, Enum.GetNames<T>/GetValues<T>, string.StartsWith(char), string.Split(char, opts), TextBox.PlaceholderText, PeriodicTimer, Memory-based Stream Read/WriteAsync, array range-slicing. - Dropped [SupportedOSPlatform] hints (net48 is single-platform). deploy/build-package.ps1: publish framework-dependent (no self-contained).
