/**
 * Linear OAuth Provider with PKCE Support
 *
 * Linear supports PKCE (Proof Key for Code Exchange) which allows
 * public clients (like CLI apps) to authenticate without a client secret.
 *
 * Linear's OAuth flow:
 * https://developers.linear.app/docs/oauth/authentication
 *
 * To configure ralph-starter's Linear OAuth app:
 * 1. Go to https://linear.app/settings/api/applications
 * 2. Create a new OAuth application
 * 3. Set redirect URI to http://127.0.0.1:52847/callback
 * 4. Copy the Client ID and set RALPH_LINEAR_CLIENT_ID env var
