Usage: plugin_health_check.php [OPTIONS]

Run health checks on a project using the appropriate plugin.

OPTIONS:
    --project-path PATH     Path to the project directory (required)
    --project-type TYPE     Project type (optional, auto-detected if not provided)
                           Valid types: joomla, nodejs, python, terraform, wordpress,
                                       mobile, api, dolibarr, generic, documentation
    --config FILE          Path to project configuration file (optional)
    --json                 Output results in JSON format (default)
    --verbose              Enable verbose logging output
    --help                 Display this help message

EXAMPLES:
    # Auto-detect project type and run health check
    plugin_health_check.php --project-path /path/to/project

    # Run health check with explicit project type
    plugin_health_check.php --project-path /path/to/project --project-type nodejs

    # Run with custom configuration
    plugin_health_check.php --project-path /path/to/project --config config.json

EXIT CODES:
    0 - Health check passed (healthy)
    1 - Health check failed (unhealthy)
    2 - Script error (invalid arguments, plugin not found, etc.)
