/**
 * Rename the current version's label. With `swap: true`, atomically move an
 * existing label out of the way (renaming the displaced version to a
 * generated `<newLabel>-prev-YYYYMMDDHHMMSS-<id>` label) and assign that
 * label to the current version. The current version's ID does not change,
 * so `cachedVersionId` is preserved.
 *
 * If `newLabel` already equals the current label, the call is a no-op and
 * returns `{ label: newLabel }` without touching the database.
 *
 * If `newLabel` is taken by another version and `swap !== true`, throws.
 *
 * The instance's `version` getter is updated only after the surrounding
 * SQL commits. When called inside `transaction(fn)`, the outer instance's
 * label is updated only if the outer transaction commits successfully; a
 * rollback leaves it at the prior label.
