Serialize snapshot items into the versioned wire text.
Function-valued fields (e.g. a container's clipFromPose) are dropped by
JSON serialization — OS-pasted clip containers arrive unclipped.
Consumers who need clips to survive the OS round-trip can translate
function ↔ registry key in their jsonReplacer/reviver pair (the
scene-serialization clipFromPoseKey precedent).
