Checks the file's mtime on each poll cycle (already running every 30s) rather than adding a separate file-watcher or admin UI. Proxmox hosts already needed no config (auto-discovered every poll); this covers the two lists that did. A parse failure logs and keeps the previous config running instead of crashing the poller. Closes #14. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
