chore(release): v1.13.0

Promote cortex-agent v1.13.0-rc.4 → v1.13.0 stable.

Claim scope: Codex host only (per user decision 2026-08-25T02:25Z).
- Codex host 21,563 receipts / 14 days / 7 consecutive days ≥100/天
- P-005 §5 Codex-only pass; DSH/PI host validation deferred to
  Phase C Stage 2 (DSH host traffic was gated on
  agent-runtime-interoperability P-007/M-031, currently stalled since
  8-19; this is not a blocker for v1.13.0 stable publication).

Candidate digest: 36bacff + release commit.
