[BREAKING] .NET: Workflow Off-Thread Execution Mode (#1233 )

* Updates to async run loop.

* fix: Workflow Onwership can be release by nonowner

* fix: Incorrect handling of blockOnPending in StreamingRun

Depending on whether we are running in streaming on non-streaming mode, we may be using the StreamingRun in different ways. Unfortunately, the only place we can really know what is the actual state of execution is in the RunEventStream implementations.

This resulted in blocking where blocking was unneeded and occasionally not-blocking when blocking was needed.

The fix is to move the logic of handling this blocking into RunEventStream implementations.

* fix: Fix cleanup on error and end run

This ensures we clean up the background resources correctly.

* fix: Ensure we let the run loop proceed when shutting down

* fix: Add timeout for Input Waiting

* fix: Make the samples properly clean up `Run`s and `StreamingRun`s

* fix: Simplify Declarative Workflow Run disposal pattern

* Also fixes missing .Disposal() in Integration tests

feat: Add name and description support to workflows (#1183 )

Add optional name and description fields to workflows in both Python and .NET implementations, matching the existing agent API pattern.

Python changes:
- Add name/description parameters to WorkflowBuilder.__init__
- Add name/description attributes to Workflow class
- Include name/description in to_dict() serialization
- Add WORKFLOW_NAME and WORKFLOW_DESCRIPTION OTEL attributes
- Add tests in test_serialization.py and test_workflow_observability.py

.NET changes:
- Add Name and Description properties to Workflow and Workflow<T>
- Add WithName() and WithDescription() fluent methods to WorkflowBuilder
- Add WorkflowName and WorkflowDescription OTEL tags
- Add test in WorkflowBuilderSmokeTests.cs

This enables applications like DevUI to display human-readable workflow names (e.g., 'Data Processing Pipeline') instead of auto-generated UUIDs (e.g., 'Workflow 50fdd917').

Fixes: #1181

Remove System.Linq.Async dependency from src assemblies (#1069 )

We shouldn't be shipping any more dependencies on this package, as it's becoming legacy, replaced by System.Linq.AsyncEnumerable.

We'll eventually want to replace it with System.Linq.AsyncEnumerable in all tests/samples, too, but that's hard to do until SK updates to use S.L.AsyncEnumerable once its 10.0.0 version is released. I did remove the package reference from tests/samples where it's not needed.
