Feature: Add Swipe-to-Dismiss / Swipe Actions list demo

[github-actions]

Summary

The README lists "Swipe lists" under "Coming Soon." Compose Material3 provides SwipeToDismissBox, the recommended API for implementing swipe-to-dismiss and swipe actions on list items.

Description

This feature would add a demo showcasing:

1. Basic SwipeToDismissBox — swipe an item left to delete it from a LazyColumn.
2. Swipe with reveal actions — swipe right to reveal an action button (e.g. "Archive").
3. Undo delete — a Snackbar with an "Undo" action after dismissal, demonstrating the interaction pattern recommended by Material Design 3 guidelines.

Proposed Location

• New component in components/swipedismiss/ or as a section within an existing "Lists" demo screen.
• Exposed from the Home screen under "Advance Lists & Animations."

Acceptance Criteria

• SwipeToDismissBox demo with directional thresholds configured.
• Background shown during swipe (e.g. red "Delete" background with icon).
• Item is removed from the list on full swipe.
• Undo Snackbar appears after deletion.
• Supports dark mode.
• Added to navigation and the Home screen list.
• README updated.
