Add Varaverk plugin scaffold (PHP, unRAID native)

Plugin lives in Plugin/ — invisible to User Script Plugin. dev_install.sh symlinks into /usr/local/emhttp/plugins/varaverk/ for development. Pages: Monitor (5s poll), Scheduler (orchs + Advanced children, toggle + cron), Config (raw editor, host-aware file access), Docs (markdown + live $VAR substitution). API endpoints: monitor.php (JSON), scheduler.php (writes schedule.json + cron.d), config.php (writes conf files with host permission check). Includes: config.php (parser, host detection, var map), scheduler.php (job tree, cron.d rebuild), monitor.php (docker, GPU, resources, fallback, transcode), docs.php (file tree, var substitution, Parsedown renderer).
