Google Calendar ICS files use UTC datetime format ending with 'Z' (e.g., 20250817T140000Z) which was failing to parse with DateTime::parse_from_str. Fixed by detecting 'Z' suffix, parsing as naive datetime, and converting to UTC with and_utc(). Also cleaned up debug logging and unused variable warnings. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
