test: Verify Codex support implementation (#45)

* feat: Add OpenAI Codex support without restructuring (#41)

Add Codex compatibility through a .codex/skills/ symlink layer that
preserves the existing domain-based folder structure while enabling
Codex discovery.

Changes:
- Add .codex/skills/ directory with 43 symlinks to actual skill folders
- Add .codex/skills-index.json manifest for tooling
- Add scripts/sync-codex-skills.py to generate/update symlinks
- Add scripts/codex-install.sh for Unix installation
- Add scripts/codex-install.bat for Windows installation
- Add .github/workflows/sync-codex-skills.yml for CI automation
- Update INSTALLATION.md with Codex installation section
- Update README.md with Codex in supported agents

This enables Codex users to install skills via:
- npx ai-agent-skills install alirezarezvani/claude-skills --agent codex
- ./scripts/codex-install.sh

Zero impact on existing Claude Code plugin infrastructure.
