• Remove System.Linq.Async dependency from src assemblies (#1069)

  We shouldn't be shipping any more dependencies on this package, as it's becoming legacy, replaced by System.Linq.AsyncEnumerable.
  
  We'll eventually want to replace it with System.Linq.AsyncEnumerable in all tests/samples, too, but that's hard to do until SK updates to use S.L.AsyncEnumerable once its 10.0.0 version is released. I did remove the package reference from tests/samples where it's not needed.

• .NET: Add AgentWorkflowBuilder group chat (#861)

  * Add AgentWorkflowBuilder group chat
  
  And fix a variety of issues along the way:
  - Use DateTime{Offset}.UtcNow rather than Now
  - AIAgentHostExecutor shouldn't be publishing empty messages
  - Sequential workflows should be flowing all history and not just the output from the previous agent as the input into the next agent
  - Renamed some of the new agent workflow methods... still not super happy with the shape, though
  - Simplified handoffs builder, e.g. using a hashset with a custom comparer instead of a dictionary
  - Improved multi-service use by trying to change assistant->user role for messages created by other agents
  - Changed MessageMerger to rely on M.E.AI's coalescing more and to avoid empty contents / text
  - Ensured that messages from ChatClientAgent include MessageId and CreatedAt timestamps
  - Avoided including instructions for agents in a handoff workflow that don't have any handoffs
  - Removed the unnecessary end function in handoffs
  - Improved naming of executors to include agent name for debuggability
  - Use "N" formatting with Guid.ToString everywhere, to avoid the unnecessary extra dash character which is also not valid in various places (like function tool names)
  - Replace `params T[]` with `params IEnumerable<T>` to make public APIs more flexible in what they consume
  
  * Address feedback
  
  - Fix unintentional provider change in sample
