Bug fixes from product test:
1. redeploy_project: BUILD_FAILED now includes explicit image pull (stop → pull → start)
2. delete_image: Distinguishes running vs stopped containers, suggests system_prune for stopped refs
3. New tool delete_container: Verify stopped state before deletion, confirmation required
Tests added for all three paths plus stopped-container edge cases.

- list_images: lists all local Docker images sorted by size desc,
shows size (human-readable), creation date, in-use marker, and
update-available marker; gracefully handles container list failure
- delete_image: accepts name:tag or image hash, blocks deletion when
image is in use by a container, requires confirmed=True to execute;
default shows a dry-run preview
- 16 unit tests covering all paths (mock DSM client)
- ruff format + check clean
