fix(rectification): ingest first-turn events without dropping day precision or claiming a unique minute

SQL kinds now match the TypeScript ledger so batch ingest can confirm dated events. Confirm no longer burns the opening focus, recap uses server date labels, and the Agent sees indistinguishable width instead of a fake unique minute.
