 * Notion OAuth Provider
 *
 * Notion's OAuth flow requires a client secret (no PKCE support).
 * For CLI apps, we recommend using manual API key configuration instead.
 *
 * https://developers.notion.com/docs/authorization
 *
 * Manual setup:
 * 1. Go to https://www.notion.so/my-integrations
 * 2. Create a new integration
 * 3. Copy the Internal Integration Secret
 * 4. Run: ralph-starter config set notion.apiKey <secret>
