I had some issues with my codex install and the desktop - might have to have a follow on, but ran out of time for it. Something to do with path maybe. |

Thanks. I've been using it for a few days with no issues. Let me know if there is anything I can do to help you replicate the behavior. |

When the Codex provider spawns `codex exec`, the subprocess inherits the parent process PATH, which is limited when launched from the desktop app. This causes failures finding Node.js and other dependencies needed by the codex CLI. Add PATH propagation using SearchPaths (matching the existing pattern in gemini_cli.rs) so the subprocess gets access to common binary locations like ~/.local/bin, /opt/homebrew/bin, and ~/.npm-global/bin. Fixes issue reported in block#6263 (comment by @Aerasyn).

Summary
Add a new CLI provider that integrates with OpenAI's Codex CLI tool, allowing users to use their ChatGPT Plus/Pro subscription through goose's interface. This follows the same pattern as the existing Claude Code provider.
Features:
codex execcommand for non-interactive modeCODEX_REASONING_EFFORTCODEX_ENABLE_SKILLS--skip-git-repo-checkviaCODEX_SKIP_GIT_CHECKSupported models (Codex CLI v0.77.0):
Configuration:

AI Assistance
This PR was developed with Claude Code assistance. All code was reviewed, tested manually with real Codex CLI integration, and validated against existing patterns in the codebase (particularly claude_code.rs). Unit tests achieve comprehensive coverage of the provider functionality.
