feat: implement local/cline.sh (#853)

Add Cline agent support on local machine. Combines local provider primitives
with Cline installation and OpenRouter credential injection.

Features:
- npm-based installation of Cline globally
- OpenRouter API key injection via OAuth or env var
- Persistent env vars in shell config (.zshrc or .bashrc)
- Sets OPENAI_BASE_URL to route through OpenRouter

Agent: gap-filler-2
