Previously, `@start` methods triggered a `FlowStartedEvent` but did not
emit a `MethodExecutionStartedEvent`. This was fine for a single entry
point but caused ambiguity when multiple `@start` methods existed.
This commit (1) emits events for starting points, (2) adds tests
ensuring ordering, (3) adds more fields to events.
