/**
* Command Code provider for pi.
*
* Connects pi to Command Code's API (https://api.commandcode.ai/alpha/generate).
*
* Authentication (pick one):
* 1. Run `/login`, then select Command Code — opens browser to commandcode.ai, auto-stores API key
* 2. Set COMMANDCODE_API_KEY environment variable
* 3. Place API key in `~/.commandcode/auth.json` or `~/.pi/agent/auth.json`
* as {"apiKey": "user_..."} or {"commandcode": "user_..."}
*
* Models are fetched from Command Code's Provider API at startup.
