v2.13

What's new

• Fixed install on immutable-OS distros (Bazzite, etc.): the NIC-WoL suspend hook write to /usr/lib/systemd/system-sleep was aborting the entire install on read-only /usr, even though it's needed only for a specific edge case (NIC Wake-on-LAN, #12). That step is now best-effort — it's skipped with a yellow warning instead, and everything else installs normally. (#14)
• Minor installer cleanup: consistent copy ordering (system units before user units), a simpler TCP port probe, and a couple of relocated/clarified comments.
