Support Codex 0.130 JSON agent messages

[tackcrypto1031]

Summary

• Accept both legacy Codex item.item_type = assistant_message and current item.type = agent_message completed-item payloads.
• Parse Codex turn.completed.usage as usage metadata while preserving existing task_complete support.

Fixes #23

Verification

• pnpm exec tsc --noEmit
• Direct parser regression script for assistant_message, agent_message, and turn.completed.usage
• pnpm build (passes; existing Turbopack NFT tracing warning remains)

Heads-up: PR #14 is also open in this area — both PRs touch src/lib/agents/argv.ts and include handling for the newer Codex agent_message / turn.completed JSON shape. This PR is the narrower parser-compatibility fix for #23, while #14 bundles that parser work with broader agent/local-font/history changes. Sharing so the authors and reviewer can compare scope before the maintainer team picks what lands.

@tackcrypto1031 Nice surgical fix for the Codex 0.130 JSON shift. The parser now accepts both legacy item_type=assistant_message and current type=agent_message in item.completed, and emits the usage meta from both task_complete and turn.completed, so older and newer Codex CLIs keep working through the same adapter. The nullish-coalescing fallback (item.item_type ?? item.type) and the inline type widening to include type?: string are exactly the right minimal touch — no other Codex branches are perturbed, and the change reads cleanly against the surrounding argv.ts shape. Verification (pnpm exec tsc --noEmit, the parser regression script for assistant_message/agent_message/turn.completed.usage, and pnpm build) is appropriately scoped for a parser bugfix in a repo without a test suite. Thanks for keeping both old and new shapes alive instead of replacing the branch — that's the right call for a CLI that ships JSON changes between point releases. Great work! 🚀

Heads-up: PR #50 is now open and also touches src/lib/agents/argv.ts for the Codex agent_message / turn.completed parser drift.

PR #50 is broader — it also includes Gemini/Copilot parsing and UI waiting logs — so this is mainly a scope coordination note for the authors and reviewer before the maintainer team picks the path to land.

Heads-up: PR #52 is now open and also touches src/lib/agents/argv.ts for the Codex agent_message / turn.completed parser drift.

PR #52 additionally includes the ConvertChip hook-order fix, so this is mainly a scope coordination note for the authors and reviewer before the maintainer team picks which path lands.
