`tags.merge`

Merge one project tag into another with sourceId, targetId, the source's expectedRevision and idempotencyKey: every transaction tagged with the source gets the target instead (once), learned rules and the tags inside a merged group move too, and the source is archived. The audit records every transaction moved.
