Feature: Module Entry Points

  Scenario: Run main module
    When I execute the __main__ module
    Then the CLI should start

  Scenario: Import main module
    When I import the __main__ module
    Then it should have a run function

  Scenario: Platform module imports CLI
    When I call ensure_cli_importable
    Then it should return the CLI module
    And the module should have a cli attribute
    And the module should have a main attribute

  Scenario: Platform handles already imported module
    When the CLI module is already imported
    And I call ensure_cli_importable
    Then it should return the cached module

  Scenario: Platform handles import errors
    When the CLI module import fails
    And I call ensure_cli_importable
    Then it should propagate the import error
