Core Versioning Rebuild, Slice 5 — Epochs and Baselines

every root has a complete anchor of its whole aggregate inside its current schema epoch: a baseline set, written by the first write after its creation, after versioning is switched back on, after a best_effort set, or after its schema changed, never in a revert set. Switching versioning off for a table discards its edit history and keeps the hard-delete snapshots.
