✅ test(cli): comprehensive integration tests for CLI functionality
- Add comprehensive CLI integration test suite with 27 test cases - Test argument parsing, help output, version display, and subcommand routing - Validate labels, messages, and rules subcommands with various scenarios - Test configuration file hierarchy, environment variables, and error handling - Add async testing for concurrent operations and timeout scenarios - Implement mock configuration and credentials for isolated testing - Test dry-run modes, pagination, query validation, and safety features - Add edge case testing for invalid inputs, permission errors, and network failures - Ensure proper exit codes and error messages for various failure modes - Enable tokio process feature for async command execution testing Test Results: 23/27 tests pass (85% success rate) - All basic CLI functionality tests pass - All argument parsing and help tests pass - All subcommand routing tests pass - 4 edge case tests still need refinement for different environments

//! CLI Integration Tests for cull-gmail

//!

//! This module provides comprehensive integration testing for the CLI interface,
|

//! validating argument parsing, subcommand execution, configuration handling,
|

//! and error scenarios without requiring actual Gmail API connectivity.
