/**
* @module Error Handling Tests - Tests for error scenarios and edge cases
*
* This test suite validates that node bin/commands.js handle errors gracefully:
* - Invalid parameter values
* - Connection failures
* - Missing required parameters
* - Type validation errors
* - Malformed inputs
*
* These tests ensure users receive clear, helpful error messages instead of
* crashes or confusing output when something goes wrong.
