.NET: [BREAKING] Enable sharing of workflow instances across concurrently executing runs (#1464 )

fix: Update WorkflowHostAgent post Checkpointing implementation (#1498 )

WorkflowHostAgent was initially implemented before Checkpointing was available. This meant that in order to support resuming, the WorkflowHostAgent needed to keep the runs around, which broke it when stricter rules about concurrent sharing of workflows during execution were introduced.

This change updates the hosting logic to release the underlying StreamingRun when the RunStreamingAsync or RunAsync are invoked, in favour of keeping the checkpointing information in the WorkflowThread to enable resumption.

- Workflow runtime can dispatch messages as either List<ChatMessage> or ChatMessage[]
- Added 10 comprehensive unit tests validating message routing behavior
- Tests ensure functionality and protect against future refactoring (issue #782)
- Updated code comments to reflect exact-type-matching requirement

Fixes issue where raw WorkflowBuilder with AIAgent nodes failed to receive
initial messages due to missing array type handler.
