Jacob Alber 2cb4137501 .NET: Remove FunctionCalls and Tool Messages from Handoff passed messages (#3811)
* Fix handoff orchestration not passing user message to handoff target agent (#3161)

Filter out internal handoff function call and tool result messages before
passing conversation history to the target agent's LLM. These messages
confused the model into ignoring the original user question.

* Add handoff tool call filtering behavior and enhance workflow builder

- Introduced HandoffToolCallFilteringBehavior enum to specify filtering behavior for tool call contents in handoff workflows.
- Updated HandoffsWorkflowBuilder to support customizable handoff instructions and tool call filtering behavior.
- Enhanced HandoffAgentExecutor to utilize new filtering options for improved message handling during agent handoffs.

* Enhance handoff message filtering logic and add unit tests for filtering behaviors

* Refactor HandoffMessagesFilter to remove unused handoff function names and enhance filtering logic for non-handoff function calls

* Refactor HandoffMessagesFilter to streamline FilterCandidateState initialization and improve clarity

* Refactor HandoffMessagesFilter to improve filtering logic and add integration tests for handoff workflows

* fix: HandoffAgentExecutor tests
