/**
 * Test Pattern: GmailAgenticSearch
 *
 * Tests the GmailAgenticSearch pattern behavior:
 * - Initial state (not scanning, idle progress, empty debug log)
 * - Output structure (ui pieces, auth state, actions)
 * - Start/stop scan state toggling
 *
 * Note: Actual Gmail API calls are not tested here - only state management.
 *
 * Run: deno task ct test packages/patterns/google/core/experimental/gmail-agentic-search.test.tsx --root packages/patterns/google --verbose
