fix(simulation): resolve duplicate examine_result field and regenerate fixtures

Removed duplicate examine_result from ObserverSnapshot (old ExamineResultEvent
superseded by ExamineResultWire). Fixed serde_default test version assertion.
Regenerated golden file and all fixture .msgpack files. 1070 Rust tests passing.
