- Prevent overwriting snapshots that have valid response codes - Ensure URL is removed from queue when snapshot update is skipped - Add last_crawled timestamp tracking for better crawl scheduling - Remove SkipIdenticalContent flag, simplify content deduplication logic - Update database schema with last_crawled column and indexes 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
