v1.0.0 - Async rewrite with incremental scanning

Summary

Major rewrite of the Substack broken link checker with significant performance improvements and new features.

Performance

• 10-20x faster with async concurrent link checking (aiohttp)
• Smart link caching - same URL across posts checked only once
• Retry logic with exponential backoff for transient failures

Incremental Scanning

• Track checked posts with --history-file
• Only scan new posts with --only-new
• Import previous results from Excel/CSV

Domain Filtering

• --skip-domains / --skip-domains-file - Assume OK (for bot-blockers)
• --broken-domains / --broken-domains-file - Auto-flag as broken

Authentication

• --cookie flag for Substack session cookie authentication

New Helper Scripts

• compare_posts.py - Find unchecked posts
• import_checked_posts.py - Import from Excel/CSV
• run_link_checker.ps1 - Windows Task Scheduler automation

Documentation

• Complete README/USAGE rewrite
• Security considerations
• Expanded troubleshooting
