Subject: [PATCH] coding-agent: workdir pattern + patience rules

- Use bash workdir param so Codex wakes up in a 'little box'
- Prevents reading unrelated files (like my soul.md lol)
- Added rule: NEVER offer to build it yourself when user asks for Codex
- gpt-5.2-codex requires medium reasoning effort

-- Prefer **tmux** even for one-shot runs; keep history + recovery.
-- For auth, run the tool’s login flow in tmux (`claude`, `codex login`, `opencode auth`).
+- **Always prefer tmux** — keeps history, survives disconnects, allows monitoring
