Relocate response sending methods ⚠️

Response sending methods such as SendOkAsync() have been ripped out of the endpoint base class for a better intellisense experience and extensibility.

Going forward, the response sending methods are accessed via the Send property of the endpoint as follows:

public override async Task HandleAsync(CancellationToken c)
{
    await Send.OkAsync("hello world!");
}

In order to add your own custom response sending methods, simply target the IResponseSender interface and write extension methods like so:

static class SendExtensions
{
    public static Task HelloResponse(this IResponseSender sender)
        => sender.HttpContext.Response.SendOkAsync("hello!");
}

This is obviously is a wide-reaching breaking change which can be easily remedied with a quick regex based find & replace. Please see the breaking changes section below for step-by-step instructions on how to migrate. Takes less than a minute.

Send multiple Server-Sent-Event models in a single stream

It is now possible to send different types of data in a single SSE stream with the use of a wrapper type called StreamItem like so:

public override async Task HandleAsync(CancellationToken ct)
{
    await Send.EventStreamAsync(GetMultiDataStream(ct), ct);

    async IAsyncEnumerable<StreamItem> GetMultiDataStream([EnumeratorCancellation] CancellationToken ct)
    {
        long id = 0;
