### PR [#2200](https://github.com/danielmiessler/Fabric/pull/2200) by [ksylvan](https://github.com/ksylvan): fix: persist Codex OAuth tokens after refresh

- Persist refreshed Codex OAuth tokens securely across processes, writing rotated credentials atomically with cross-process locks.
- Reload stored tokens before refresh and return valid in-memory tokens first, preventing stale disk values from overwriting fresh credentials.
- Reuse valid refresh tokens before launching interactive authentication, requiring account identifiers and unexpired tokens for fast-path reuse.
- Preserve existing environment values, save environment files atomically while holding locks, and enforce secret-only permissions.
- Reactivate configured vendors and surface configuration and provider failures immediately, with localized Codex prompts and persistence errors.
