* feat: Define Workflow and Executor APIs
* feat: Define IExecutionContext and Events
* feat: Simple Workflow Demos
* refactor: Move Workflows classes to separate assembly
* feat: Move FanOut/In to LowLevel API with new semantics
* feat: Implement Local Execution
* refactor: Assembly name .Workflow => .Workflows
* feat: Enable Default Message Handling
* also lifts Bind in MessageHandlerInfo to better be able to direclty invoke handlers (for AOT, later)
* feat: Implement StreamingHandle APIs
This allows the user to respond to WorkflowEvents with external messages, enabling HIL.
* feat: Add checks for duplicate edges and chain cycles
* feat: Add built-in WorkflowEvents
* refactor: Pull classes into own files
* refactor: Simplify Disposal pattern in Executor
* refactor: Break EdgeRunner file into per-type files
* refactor: Use Throw.IfNull()
* refactor: Remove AddLoop()
Per https://github.com/microsoft/agent-framework/pull/272#discussion_r2241739079 we decided this was not very useful.
* refactor: Normalize use of ValueTask
* fix: Build Break from removing .AddLoop
* refactor: Explicit routing and RouteBuilder
Split out reflection from MessageRouter implemention into build phase, enabling AOT compilation to drive RouteBuilding without reflection.
* test: Add Reflection/Invocation tests
* fix: Terminate on Completion event
* refactor: Update public API surface
* feat: Add support for external requests
* feat: Support hosting AIAgent instances in Workflows
* fix: Fix routing to go through Executor.ExecuteAsync
* test: Update samples for "must SendMessage" semantics
* Add invoking samples to unit tests to avoid future breaks
* fix: ExternalRequest should block Workflow completion
* feat: Normalize API surface against Python
* Also adds xmldoc to all public APIs
* refactor: Normalize UnitTest and Sample namespaces
* fix: Formatting
* refactor: Normalize project/folder names
* feat: Remove DynamicCodeExecution from ValueTaskTypeErasure
* fix: Fix ILTrim warnings
* docs: Add missing docs and fix typos
* feat: Hosted Agents should report Run events
* fix: Fix type propagation for ILTrim changes
* refactor: Simplify DynamicallyAccessedMembers annotations
* sample: Use static-Type construction of InputPort
* feat: Support non-Streaming Run Mode
* test: Add test for non-streaming execution
* refactor: Remove unused types
* refactor: Simplify Event and EdgeData type hierarchies
* feat: Add Switch (=Conditional Edge Group) control flow
* feat: Make .NET AutoSend the MessageHandler result
* feat: Implement State APIs
* refactor: Simplify public namespaces and code organization
* refactor: Reconcile .NET and Python names
