Ship a first-class OpenAI Codex plugin entry point. Mirrors the
existing Claude Code and Cursor plugin manifests and reuses the
shared ./skills/ directory - no skill duplication.
Manifest declares the spec-required interface block (displayName,
developerName, category, capabilities, logo, logoDark) and points
skills at the existing skills/ tree. The logo pair (Go cyan on
light, slate on dark) is a placeholder; the design is intentionally
neutral so a real brand mark can drop in without rework.
Version pins to 2.0.1 to match .claude-plugin/, .cursor-plugin/ and
gemini-extension.json - all four must stay in lockstep per CLAUDE.md
Plugin Configuration.
