Stable Codex adds opt-in Guardian history and safer session recovery

Codex 0.160.0 ships opt-in Guardian retrieval of earlier user instructions and handoff-aware review context. Both features are disabled by default and remain bounded by current parent policy. The stable release also restores saved session permissions, supports projectless sessions when policy permits, and resumes unsent queued messages only after uncertain submissions are resolved. This is a stable release, distinct from the newer experimental alpha line.
