codex: add harness home bootstrap

[AceHack]

Summary

• Adds .codex/AGENTS.md as the Codex harness-specific addendum.
• Adds .codex/CURRENT-codex.md as the compact current-state handoff surface.
• Updates .codex/README.md and AGENTS.md to mark the Codex addendum as present.

Verification

• bunx markdownlint-cli2 AGENTS.md .codex/README.md .codex/AGENTS.md .codex/CURRENT-codex.md
• git diff --check

Note: full Prettier check on AGENTS.md / .codex/README.md reports pre-existing repository-wide Markdown style churn (asterisk-to-underscore/table formatting); I did not run --write to avoid unrelated rewrites.

Pull request overview

This PR bootstraps a repo-native “home” for the OpenAI Codex harness by adding a Codex-specific addendum and a compact current-state handoff surface under .codex/, and wiring the universal handbook (AGENTS.md) to acknowledge the new addendum.

Changes:

• Add .codex/AGENTS.md (Codex harness addendum) and .codex/CURRENT-codex.md (current-state handoff).
• Update .codex/README.md to document the new files and shared-machine worktree/heartbeat discipline.
• Add a claim file for the work and update AGENTS.md to mark the Codex addendum as present.

	log(`warning: removing stale lock; lock_age=${Math.round(ageMs / 1000)}s ttl=${Math.round(lockTtlMs / 1000)}s`);
	rmSync(lockDir, { recursive: true, force: true });
	mkdirSync(lockDir);

Keep active lock while owning process is alive

The stale-lock branch removes lockDir solely based on age, even when the PID in metadata is still alive. With this commit’s defaults (StartInterval=60s, ZETA_CODEX_LOOP_LOCK_TTL_SECONDS=120, ZETA_CODEX_LOOP_CODEX_TIMEOUT_SECONDS=300), a normal Codex run lasting over 2 minutes will have its live lock deleted by a later tick, allowing overlapping executions and concurrent writes/logging despite the script claiming non-overlap safety.
