Enhance project metadata and refactor core classes

Updated project files for `Beam.Dynamic`, `Beam.Exports`, `Beam.Temporary.Cli`, and `Beam` to include additional metadata and specific package versions. Refactored `DataBindings` and `ResolvedBindings` to records, added a new `Text` property in `Binding.cs`, and introduced `ParseNumbers` in `OnlineCleaner`. New classes `PuppetContext` and `PuppetUnitDownloader` added for Playwright integration. Introduced `ImmutableState` struct and `UnitDownloaderBinary` class for improved download management. Updated tests in `UnitTest1.cs` for number localization. Added `Beam.Puppeteer` project to the solution.
