release: v0.1.6

Since v0.1.5:
- fix(messages): Claude models no longer 400 with 'Invalid signature in
  thinking block' — thinking is replayed only for the active tool loop
  and only when genuinely signed (cross-backend/cross-model histories
  are stripped)
- fix(codex): ChatGPT Codex no longer 400s with 'System messages are
  not allowed' — system prompts ride the instructions field and
  encrypted reasoning is requested for stateless replay
- docs: AGENTS.md records both wire contracts
