Addresses remaining CI review feedback from HAL9001 on PR #8304:
1. Moved all cleveragents imports from inside function bodies to module-level
in features/steps/container_clone_into_steps.py (5 functions fixed)
2. Moved BUILTIN_TYPES import from inside step_look_up_in_builtin_types()
to module level in features/steps/devcontainer_sandbox_strategy_steps.py
3. Removed redundant inline import of EMPTY_CONTENT_HASH and BaseResourceHandler
inside diff() method of devcontainer.py (already available at module level)
4. Fixed stale docstring referencing old 'detected' terminology in
robot/helper_devcontainer_lifecycle.py cmd_transition_valid()
All files pass ruff format and ruff check.
- Adds a --clone-into option to the container-instance command to clone repository contents into a specified path during container setup.
- Fixes the devcontainer-instance sandbox strategy to ensure proper isolation, correct mount permissions, and deterministic behavior across environments.
- Updates related validation and error handling to reflect the new option and sandbox changes.
