Codex QA

QA the omo Codex Light edition (packages/omo-codex/, shipped as lazycodex). We exercise OUR plugin in a REAL Codex while touching nothing of the user's setup: an isolated CODEX_HOME + a local mock model means no real API call and the real ~/.codex is never read or written. Each helper script ships a --self-test that asserts its scenario against the live machine, so the scripts are both the QA tools and their own regression checks.

Verified against codex-cli 0.140.0 (node, jq, tmux, bun on macOS). Confirm with codex --version; check a flag with codex <cmd> --help.
