USAGE:
    $0 [OPTIONS] [GENERATORS...]

OPTIONS:
    -h, --help              Show this help message
    -l, --list              List available generators
    -p, --plan              Show execution plan
    -v, --validate          Validate dependencies only
    --tenant-id ID          Generate data for specific tenant ID
    --tenant-slug SLUG      Generate data for specific tenant slug
    --skip-validation       Skip dependency validation
    --dry-run               Show what would be done without executing

GENERATORS:
    Specify which generators to run. If none specified, runs all in dependency order:
    core accounts hr patients emr lab radiology pharmacy appointments billing inpatients inventory facility_management

EXAMPLES:
    $0                          # Run all generators
    $0 core accounts patients   # Run specific generators
    $0 --tenant-id 1            # Generate data for tenant ID 1
    $0 --list                   # List available generators
    $0 --plan                   # Show execution plan
    $0 --validate               # Validate dependencies only

DEPENDENCY ORDER:
    1. core (tenants)
    2. accounts (users)
    3. hr (employees/departments)
    4. patients (patients)
    5. emr, lab, radiology, pharmacy (clinical data - parallel)
    6. appointments (needs patients + providers)
    7. billing (needs patients + encounters)
    8. inpatients (needs patients + staff)
    9. inventory (independent)
    10. facility_management (management command)
