v2.20.8-codex.1 - Initial Codex Distribution Split

🎯 What's Changed for You

Codex users can now install and operate Harness from a standalone Codex-focused repository.

Before	After
Codex setup depended on Claude plugin repository structure	Codex distribution is managed in an independent repository with explicit sync and validation

Added

• Independent codex-harness repository bootstrap
• Distribution contract file: codex-dist.manifest.json
• One-way sync script: scripts/sync-from-claude.sh
• Install script: scripts/setup-codex.sh
• Integrity/smoke test suite under tests/
• Compatibility mapping table in docs/COMPATIBILITY.md

Fixed

• Eliminated ambiguity in release operation by defining strict Claude -> Codex sync direction
