/**
 * hmem v2 — entries & nodes CRUD with ULID identity.
 *
 * Identity model (master-plan Goal #1): the ULID `uid` is the immutable primary
 * key and the only thing references point at; the human `label` (`P0048`) is
 * mutable display sugar. `seq` is a monotonic per-prefix counter — soft-deleted
 * labels are NEVER recycled, so a reference to a deleted entry stays dead rather
 * than silently resolving to a different entry.
 *
 * In-prose refs are stored as `{{u:<ULID>}}` tokens. `renderRefs` turns those
 * back into the entry's *current* label at read time, so renaming a label
 * rewrites zero stored text.
