fix: correct provider setup descriptions for browser-based auth

All major providers (Claude, Codex, Gemini, OpenCode) use browser-based
OAuth authentication, not manual API keys:
- Run the CLI command
- Browser opens for sign-in
- Auth tokens saved automatically

Also added post_install_note for Ollama to show how to add the provider
after installing.
