Merge embedded file provider; bump package version

Create a ManifestEmbeddedFileProvider for the executing assembly and, if an existing FileProvider is set, wrap both with a CompositeFileProvider; otherwise assign the manifest provider and continue checking environment/wwwroot as before. This ensures embedded resources are available alongside any configured file provider. Also bump package version to 10.2026.316.550.
