* Update AIAgent,Run to take IEnumerable instead of IReadonlyCollection
* Address PR comment.
* Cast to IReadonlyCollection since this is typically all that is required to avoid unecessary allocation.
* Update OrchestratingAgent protected methods as well.
* fix: MessageMerger crashes when there are no dangling messages
* refactor: Better logic for AgentId in Workflow-as-Agent
If the parent "agent" instance received an Id or Name when being instantiated, we should avoid stomping over it with the subagents' ids. But if there is no parent identifier, and only a single subagent yielded identified messages, pull that in.
When checkpointing we did not persist the set of instantiated executors. This means, in turn, when we restore from a checkpoint when using Resume(Stream) rather than restoring a checkpoint in the context of an already existing (Streaming)Run, the executors never got reinstantiated and there were no executors to notify that a state should be loaded.
The fix is to ensure we persist the list and reinstantiate the executors on rehydration.
* Also adds a rehydration restore test
* feat: Improve DevEx for simple Executors
* Add abstract types for executors that will only handle one type of message
* Add FunctionExecutor and configuration capability on delegates
* Add support for late-instantiated Executors
* refactor: Remove open-typed extension method
* refactor: Switch to TaskFactory pattern for async--from-sync
* docs: Update XML docs for publics and fix formatting
* refactor: Better naming for ExecutorIsh configuration methods
* docs: Fix typo in ExecutorIshConfigurationExtensions.ConfigureFactory
* fix: FanIn Edge does not work
We were not creating the state for FanIn edge in EdgeMap correctly, leading to crashes. After fixing that, it turns out the logic in FanInEdgeRunner was only forwarding the last message, not all of them.
* fix: Remove duplicate code and fix typo
The previous fix for the aggregation in AIAgentHostExecutor has a bug wherein we only include the first update from a ChatMessage in the outgoing "collected" message.
The fix is to ensure we put the collected updates into the message before sending it out.
* feat: Make WorkflowBuilder more intutitve
Right now Executorish binding has some unintutitive behaviour. When a user adds an eecutor with an id of an executor that already exists, we silently replace it, if the user provides it inside of add_edge. When a user introduces an executor via an unbound id, the user must bind it via BindExecutor, even though the registration is created implicitly when an edge id added.
The change will remove the invisible update in favor of a "best efforts" check of type and instance equality.
* Expand errors when rebinding to disallowed
