5.0.0

What's Changed

Breaking changes

• IMediator now inherits IAsyncDisposable — any code implementing IMediator directly must add DisposeAsync(). Consumers of IMediator are unaffected.

Bug fixes

• MediatorBuilder.RegisterHandlers(Assembly) now correctly picks up IStreamCommandHandler<,> implementors (previously silently skipped, causing NoHandlerFoundException at runtime)
• Fixed broken return value in RequestPipe.ConnectToHandler IAsyncEnumerable branch (Task.FromResult(r) → r)
• PipeHelper.GetResultFromTask now throws InvalidOperationException with a descriptive message instead of bare Exception

Improvements

• Mediator implements IAsyncDisposable with async-path fallback via DisposeAsync()
• Removed unnecessary reflection in ReceiveContext.PublishAsync — publishPipe.Connect() is now called directly through the interface
• [EnumeratorCancellation] added to ConnectStream async-iterator methods so cancellation tokens are correctly forwarded to consumers
• Count() LINQ extension replaced with .Count property (O(1)) at 4 sites in CommandReceivePipe and RequestPipe
• ReceiveContext.MetaData uses ??= operator
• Internal class GlobalRececivePipeConfigurator renamed to GlobalReceivePipeConfigurator (typo fix)
