zenfg-snapshot upgrade notes

Package API versions and Snapshot wire versions are independent. The historical changes below apply to the named releases, not to every current integration.

Snapshot 1.2 and package 0.1.1

Snapshot 1.2 remains canonical. Package 0.1.1 fixes ancestry validation without changing valid captures or codec APIs. Supported 1.1 inputs are validated before migration; CPU becomes not-collected. Legacy V0 and Candidate V1 remain readable. Canonical 1.0 and unknown versions remain rejected. Validation and serialization alone do not migrate. Preserve provenance and extensions; never change a version number to invent absent capture facts.
