"""Tests for workflow automation with Claude integration.

This test file implements TDD for enhanced workflow commands that use
Claude to intelligently analyze emails and suggest/execute actions.

Tests verify that:
1. Workflows can use Claude for intelligent analysis
2. Actions are previewed before execution
3. User confirmation required for actions
4. Multiple built-in workflows available
