Fixed two critical issues with HA monitoring: 1. False positive quorum errors - corosync-quorumtool not in cron PATH 2. Unwanted cron emails from PVE::Notify INFO messages to STDERR Changes: - Set proper PATH including /usr/sbin for corosync-quorumtool - Split notification code: verbose shows all, non-verbose redirects STDERR to /dev/null - Prevents cron from sending duplicate notification emails 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
