Enhance async capabilities and refactor project structure

Updated project files for `Beam.Dynamic`, `Beam.Exports`, `Beam.Puppeteer`, `Beam.Temporary.Cli`, and `Beam` to include new XML headers, reorganize property groups, and add project references.

Modified `PuppetedUnitDownloader` to support additional parameters for async transformers. Changed return types in `CommonTransformers` to `AsyncTransformer` for asynchronous processing.

Significant refactoring in `DownloadBuilder`, `DownloadContext`, and `DownloadContextBuilder` to introduce generic parameters and improve context management. Updated `SequentialDownloader`, `SequentialFragmentDownloader`, and `UnitDownloader` to accommodate new async transformer types.

Introduced `TypeExtensions` for unique type name generation and added `UnitFragmentDownloaderBinary` for handling binary downloads. Updated solution file to include the new `aeqw89.Beam` project, ensuring proper references across the solution.

These changes enhance the asynchronous capabilities of the Beam library, improve type safety, and streamline the downloading process.
