.NET: Fixing issue where OpenTelemetry span is never exported in .NET in-process workflow execution (#4196 )

* 1. Add reproduction test for issue #4155: workflow.run Activity never stopped in streaming OffThread path

The WorkflowRunActivity_IsStopped_Streaming_OffThread test demonstrates that
the workflow.run OpenTelemetry Activity created in StreamingRunEventStream.RunLoopAsync
is started but never stopped when using the OffThread/Default streaming execution.
The background run loop keeps running after event consumption completes, so the
using Activity? declaration never disposes until explicit StopAsync() is called.

2. Fix workflow.run Activity never stopped in streaming OffThread execution (#4155)

The workflow.run OpenTelemetry Activity in StreamingRunEventStream.RunLoopAsync
was scoped to the method lifetime via 'using'. Since the run loop only exits on
cancellation, the Activity was never stopped/exported until explicit disposal.

Fix: Remove 'using' and explicitly dispose the Activity when the workflow reaches
Idle status (all supersteps complete). A safety-net disposal in the finally block
handles cancellation and error paths.

* Add root-level workflow.session activity spanning run loop lifetime\n\nImplements two-level telemetry hierarchy per PR feedback from lokitoth:\n- workflow.session: spans the entire run loop / stream lifetime\n- workflow_invoke: per input-to-halt cycle, nested within the session\n\nThis ensures the session activity stays open across multiple turns,\nwhile individual run activities are created and disposed per cycle.\n\nAlso fixes linkedSource CancellationTokenSource disposal leak in\nStreamingRunEventStream (added using declaration)."

* Address Copilot review: fix Activity/CTS disposal, rename activity, add error tag\n\n1. LockstepRunEventStream: Remove 'using' from Activity in async iterator\n   and manually dispose in finally block (fixes #4155 pattern). Also dispose\n   linkedSource CTS in finally to prevent leak.\n2. Tags.cs: Add ErrorMessage (\"error.message\") tag for runtime errors,\n   distinct from BuildErrorMessage (\"build.error.message\").\n3. ActivityNames: Rename WorkflowRun from \"workflow_invoke\" to \"workflow.run\"\n   for cross-language consistency.\n4. WorkflowTelemetryContext: Fix XML doc to say \"outer/parent span\" instead\n   of \"root-level span\".\n5. ObservabilityTests: Assert WorkflowSession absence when DisableWorkflowRun\n   is true.\n6. WorkflowRunActivityStopTests: Fix streaming test race by disposing\n   StreamingRun before asserting activities are stopped.\n7. StreamingRunEventStream/LockstepRunEventStream: Use Tags.ErrorMessage\n   instead of Tags.BuildErrorMessage for runtime error events."

* Review fixes: revert workflow_invoke rename, use 'using' for linkedSource, move SessionStarted earlier\n\n- Revert ActivityNames.WorkflowRun back to \"workflow_invoke\" (OTEL semantic convention contract)\n- Use 'using' declaration for linkedSource CTS in LockstepRunEventStream (no timing sensitivity)\n- Move SessionStarted event before WaitForInputAsync in StreamingRunEventStream to match Lockstep behavior"

* Improve naming and comments in WorkflowRunActivityStopTests"

* Prevent session Activity.Current leak in lockstep mode, add nesting test

Save and restore Activity.Current in LockstepRunEventStream.Start() so the
session activity doesn't leak into caller code via AsyncLocal. Re-establish
Activity.Current = sessionActivity before creating the run activity in
TakeEventStreamAsync to preserve parent-child nesting.

Add test verifying app activities after RunAsync are not parented under the
session, and that the workflow_invoke activity nests under the session."

* Fix stale XML doc: WorkflowRun -> WorkflowInvoke in ObservabilityTests

.NET: Fix JSON arrays of objects parsed as empty records when no schema is defined (#4199 )

* 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).

.NET: [BREAKING] Workflows API Review Naming Changes (Part 1?) (#4090 )

* refactor: Normalize Run/RunStreaming with AIAgent

* refactor: Clarify Session vs. Run -level concepts

* Rename RunId to SessionId to better match Run/Session terminology in AIAgent
* [BREAKING]: Will break existing checkpointed sessions in CosmosDb due to field rename

* refactor: Rename and simplify interface around getting typed data out of ExternalRequest/Response

* Also adds hints around using value types in PortableValue

* refactor: Rename AddFanInEdge to AddFanInBarrierEdge

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.

* refactor: AsAgent(this Workflow, ...) => AsAIAgent(...)

* misc - part1: SwitchBuilder internal

.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.

- 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 streaming path to include chat history in messages sent to chat client (#3798 )

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.

.NET: Workflow telemetry opt in (#3467 )

* feat(workflows): Make telemetry opt-in via WithOpenTelemetry()

- Add WorkflowTelemetryOptions class with EnableSensitiveData property
- Add WorkflowTelemetryContext to manage ActivitySource lifecycle
- Add WithOpenTelemetry() extension method on WorkflowBuilder
- Update all workflow components to use telemetry context:
  - WorkflowBuilder, Workflow, Executor
  - InProcessRunnerContext, InProcessRunner
  - LockstepRunEventStream, StreamingRunEventStream
  - All edge runners (Direct, FanIn, FanOut, Response)
- Telemetry is now disabled by default
- Users must call WithOpenTelemetry() to enable spans/activities

BREAKING CHANGE: Workflow telemetry is now opt-in. Users who relied on
automatic telemetry must add .WithOpenTelemetry() to their workflow builder.

* refactor: Pass telemetry context as parameter instead of via interface

- Remove IWorkflowContextWithTelemetry interface
- Add internal ExecuteAsync overload that accepts WorkflowTelemetryContext
- Public ExecuteAsync delegates with WorkflowTelemetryContext.Disabled
- InProcessRunner passes TelemetryContext when calling ExecuteAsync
- BoundContext now implements IWorkflowContext (not the removed interface)

* Add optional ActivitySource parameter to WithOpenTelemetry

Allow users to provide their own ActivitySource when enabling telemetry,
giving them better control over the ActivitySource lifecycle. When not
provided, the framework creates one internally (existing behavior).

Changes:
- Add optional activitySource parameter to WithOpenTelemetry() extension
- Update WorkflowTelemetryContext to accept external ActivitySource
- Add unit test for user-provided ActivitySource scenario

* Add component-level telemetry control with disable flags

Allow users to selectively disable specific activity types via
WorkflowTelemetryOptions. All activities are enabled by default.

New disable flags:
- DisableWorkflowBuild: Disables workflow.build activities
- DisableWorkflowRun: Disables workflow_invoke activities
- DisableExecutorProcess: Disables executor.process activities
- DisableEdgeGroupProcess: Disables edge_group.process activities
- DisableMessageSend: Disables message.send activities

Added helper methods to WorkflowTelemetryContext for each activity type
and updated all activity creation sites to use them.

* Implement EnableSensitiveData to log executor input/output

When EnableSensitiveData is true in WorkflowTelemetryOptions, executor
input and output are logged as JSON-serialized attributes in the
executor.process activity.

New activity tags:
- executor.input: JSON serialized input message
- executor.output: JSON serialized output result (non-void only)

Added suppression attributes for AOT/trimming warnings since this is
an opt-in feature for debugging/diagnostics.

* Refactor activity start methods to centralize tagging logic

Move tagging logic into WorkflowTelemetryContext methods:
- StartExecutorProcessActivity now accepts executorId, executorType,
  messageType, and message; sets all tags including executor.input
  when EnableSensitiveData is true
- Added SetExecutorOutput method to set executor.output after execution
- StartMessageSendActivity now accepts sourceId, targetId, and message;
  sets all tags including message.content when EnableSensitiveData is true

Simplified Executor.cs and InProcessRunnerContext.cs by removing
inline tagging code. Added message.content tag constant.

* Revert Python changes

* Update samples and code cleanup

* Fix file formatting

* Add comment

* Add telemetry configuration to declarative workflow

* Remove delays in tests

* Address comments
