Add manifest resource extensions to AssemblyExtensions

[Copilot]

Ports two utility methods from DotnetRuntimeBootstrapper into PowerKit's AssemblyExtensions, each with a sync and async variant.

New methods

• GetManifestResourceString(resourceName, encoding) — reads an embedded resource as a string using the specified encoding
• GetManifestResourceString(resourceName) — reads an embedded resource as a UTF-8 string (delegates to the encoding overload)
• GetManifestResourceStringAsync(resourceName, encoding, ct) — async variant with encoding
• GetManifestResourceStringAsync(resourceName, ct) — async UTF-8 variant (delegates to the encoding overload)
• ExtractManifestResource(resourceName, filePath) — copies an embedded resource to a file
• ExtractManifestResourceAsync(resourceName, filePath, ct) — async variant

All methods throw MissingManifestResourceException when the resource name isn't found.

var json = Assembly.GetExecutingAssembly().GetManifestResourceString("MyApp.config.json");
var latin = Assembly.GetExecutingAssembly().GetManifestResourceString("MyApp.data.txt", Encoding.Latin1);

await Assembly.GetExecutingAssembly().ExtractManifestResourceAsync("MyApp.bootstrap.exe", targetPath);

Fixed in 2ae2487 — switched to await File.ReadAllTextAsync(tempFile.Path).

Pull request overview

Ports manifest-resource helpers into PowerKit.Extensions.AssemblyExtensions to simplify reading embedded resources as UTF-8 strings and extracting them to files, with sync/async variants.

Changes:

• Add GetManifestResourceString* and ExtractManifestResource* extension methods on Assembly.
• Add a new embedded test resource (TestResource.txt) to the test project.
• Add tests validating string reading and extraction behavior against the embedded resource.
