This PR cleans up the monolithic README by breaking it into a set navigable pages under docs/ (install, getting started, configuration, authentication, sandboxing and approvals, platform details, FAQ, ZDR, contributing, license). The top‑level README is now more concise and intuitive, (with corrected screenshots). It also consolidates overlapping content from codex-rs/README.md into the top‑level docs and updates links accordingly. The codex-rs README remains in place for now as a pointer and for continuity. Finally, added an extensive config reference table at the bottom of docs/config.md. --------- Co-authored-by: easong-openai <easong@openai.com>
