One targeted fix, big visible difference: on desktop, gateway-style providers never showed their real catalogs.

• Desktop model picker: live catalogs for grouped providers. LLM Gateway, OpenRouter, Copilot, GitHub Models, opencode-zen, the local proxy, and Vercel AI Gateway all listed only a short hardcoded fallback set on desktop — regardless of your key or login. The picker's probe asked these providers the wrong question (their flat model call intentionally returns nothing; the grouped catalog is the real one). It now fetches the grouped catalog: LLM Gateway shows its full ~232 models, OpenRouter ~347, and DevPass logins see everything their plan allows. The TUI was never affected.
