* fix: use HasSchema check in DetermineElementType to prevent empty records
When parsing JSON arrays containing objects without a predefined schema,
`DetermineElementType()` was creating a `VariableType` with an empty
(non-null) schema via `targetType.Schema?.Select(...) ?? []`. This caused
`ParseRecord` to take the schema-based parsing path, iterating over zero
schema fields and silently discarding all JSON properties.
The fix checks `targetType.HasSchema` and falls back to
`VariableType.RecordType` (which has `Schema = null`) when no schema is
defined, ensuring `ParseRecord` takes the dynamic `ParseValues()` path
that preserves all JSON properties.
Closes#4195
* test: add regression tests for schema-less JSON array-of-objects parsing (#4195)
Add two regression tests to JsonDocumentExtensionsTests:
1. ParseRecord_ObjectWithArrayOfObjects_NoSchema_PreservesNestedProperties
- Parses a JSON object containing an array of objects using
VariableType.RecordType (no schema) and verifies that nested
object properties (name, role) are preserved in each element.
- This is the exact scenario from issue #4195 where objects in
arrays were being returned as empty dictionaries.
2. ParseList_ArrayOfObjects_NoSchema_PreservesProperties
- Parses a JSON array of objects directly via ParseList with
VariableType.ListType (no schema) and verifies all properties
are preserved.
Both tests follow the existing Arrange/Act/Assert pattern and would
have failed before the DetermineElementType() fix (empty dictionaries
instead of populated ones).
When converting base AgentRunOptions to ChatClientAgentRunOptions, the middleware
now preserves AllowBackgroundResponses, ContinuationToken, and AdditionalProperties
in addition to ResponseFormat.
Added unit test verifying all properties are preserved during the conversion.

This will prevent a breaking change later when we introduce a programmable FanIn edge, analogous to the FanOut edge's EdgeSelector.
The goal, in the long run is to support a number of different FanIn scenarios, with naive FanIn (no barrier) by default, similar to FanOut.

* 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
* [BREAKING] refactor: Decouple Checkpointing and Execution APIs
With this change, Checkpointing becomes an property of an IWorkflowExecutionEnvironment. This lets environments that are tightly-coupled to their CheckpointManager avoid needing to present APIs that would not work (e.g. taking in an InMemory CheckpointManager for Durable Tasks, for example)
* refactor: Normalize IsCheckpointingEnabled naming
Track the last CheckpointInfo in InProcessRunner so that newly created
checkpoints reference their parent. When resuming from a checkpoint,
the resumed-from checkpoint becomes the parent of the next checkpoint.
Adds tests verifying:
- First checkpoint has null parent
- Subsequent checkpoints chain parents correctly
- Checkpoint after resume references the resumed-from checkpoint

RunCoreStreamingAsync was passing inputMessagesForProviders (which lacks
chat history) to GetStreamingResponseAsync instead of
inputMessagesForChatClient (which includes chat history). This caused
streaming runs to lose conversation context on subsequent calls.
The non-streaming path (RunCoreAsync) already correctly used
inputMessagesForChatClient. This aligns the streaming path to match.
Also adds a unit test that validates chat history is included in
messages sent to the chat client during streaming on subsequent calls.
