Claude-Codex-Gemini tri-model orchestration via /ask codex + /ask gemini, then Claude synthesizes results

# CCG - Claude-Codex-Gemini Tri-Model Orchestration

CCG routes through the canonical `/ask` skill (`/ask codex` + `/ask gemini`), then Claude synthesizes both outputs into one answer.

Use this when you want parallel external perspectives without launching tmux team workers.

## When to Use

- Backend/analysis + frontend/UI work in one request
- Code review from multiple perspectives (architecture + design/UX)
- Cross-validation where Codex and Gemini may disagree
- Fast advisor-style parallel input without team runtime orchestration

## Requirements

- **Codex CLI**: `npm install -g @openai/codex` (or `@openai/codex`)
- **Gemini CLI**: `npm install -g @google/gemini-cli`
- `omc ask` command available
- If either CLI is unavailable, continue with whichever provider is available and note the limitation

## How It Works
