Pull request overview

This PR removes intermediate snapshot functionality from both synchronous and asynchronous agent loops, deferring snapshots to only occur upon task completion. The change eliminates unsaved state warnings that were previously generated during loop iteration and at final processing.

Key Changes:

• Removed intermediate snapshot logic and associated warning generation from loop iterations
• Eliminated final snapshot checks after loop completion
• Cleaned up unused imports (create_unsaved_warning, is_live_root)
