docs: update the wiki to 0.5.1 and apply ASD-STE100 The wiki described version 0.1.0. It told the reader that the packages were not on NuGet, that RamblaList was a future phase, that MaxRefreshRate did nothing, and that Avalonia was not available. It also told the reader to copy a sample class that the repository deleted. All the pages now use Simplified Technical English (ASD-STE100): short sentences, active voice, one meaning for each technical name. The new Glossary page declares the technical names, as the standard requires. New pages: Schedulers, Collections, Async Commands, Diagnostics, Glossary. Core Semantics now covers the collections, the async commands and the throttling scheduler.
