v3.20.2

Fixed

• handoff-pneuma now actually shows up in Codex — Codex couldn't find it because we installed a custom prompt at ~/.codex/prompts/handoff-pneuma.md, but OpenAI deprecated custom prompts and they silently stop appearing in the slash menu (openai/codex#15941) — and even when they work they surface as /prompts:handoff-pneuma, never /handoff-pneuma. Codex now gets handoff-pneuma as a proper skill at ~/.agents/skills/handoff-pneuma/SKILL.md (the user-level Agent Skills location Codex scans), invokable via /skills, $handoff-pneuma, or implicitly from its description. Installing also migrates away any stale prompt we previously wrote. Claude Code is unchanged (/handoff-pneuma slash command). Verified end-to-end against Codex 0.137.0.
