Mark TaskExtensions and new helpers as [Obsolete]

Browse Source 
Marked TaskExtensions class and all its methods as [Obsolete] with guidance to implement Mediator behaviors instead. Added new [Obsolete] extension methods for null/empty checks and chaining. Introduced an [Obsolete] Exceptions class with factory methods for common exceptions. All changes are intended for legacy or transitional use only.
