New secubox-app-smbfs package for SMB/CIFS remote directory management with smbfsctl CLI (add/remove/mount/umount/test/status), UCI config, auto-mount init script, and Jellyfin/Lyrion media path integration. Glances LXC: host bind mounts (/rom, /overlay, /boot, /srv), Docker socket fix (symlink loop), fs plugin @exit_after patch, hostname/OS identity, pre-generated /etc/mtab. KISS READMEs for secubox-app-jellyfin and luci-app-jellyfin. Planning files updated with Domoticz IoT, AI Gateway strategy, App Store P2P emancipation, and v2 roadmap items.
