Add Codex support to Refact Toolkit

[masoudgolchin]

Refact Toolkit can now be installed in Codex from the same repository as Claude Code. All nine packs share their skill files, scripts, and references. Native Codex manifests and a marketplace catalog make the packs discoverable without an installation build step.

• Add the shared refact-toolkit entry skill and Codex instructions for plugin management, project settings, paths, agent briefs, and Refact Control setup.
• Keep Claude hooks in explicit Claude manifest entries. Codex loads the shared skills without the Claude transcript uploader or language-server installers.
• Add project-specific enable/disable examples, installation and update documentation, and generated release metadata with CI checks.
• Bump the nine pack versions and fix the existing base manifest/catalog version mismatch.

Validation: all nine manifests pass the Codex and Claude validators; the repository checker validates 42 skills; all three release/preflight tests and GitHub CI pass. Installation from this GitHub branch succeeds: all 32 installed base files match the published commit, and a fresh Codex task loads its 11 skills. In a trusted project, toggling base@refact-os removes or restores its skills in the rendered task input while the user-level installation stays enabled. External service workflows were not run end to end.

To review this branch in Codex:

codex plugin marketplace add refactco/claude-toolkit --ref feat/codex-plugin-support
codex plugin add base@refact-os

Start a new task and ask: “Use the Refact toolkit for this project.” See docs/codex.md for project overrides and updates.
