README.md: maintenance guide describing how the adac PipeWire audio
hub is wired together — the four audio paths, the five config drop-ins,
services, firmware, and common maintenance tasks. Written as a mental
model for upkeep rather than install/troubleshooting commands.
root-README.md: short redirect telling anyone on the root account to
log in as the `user` account (PipeWire is a per-user service), pointing
to the maintenance guide.
These mirror the files deployed at /home/user/README.md and
/root/README.md on the Pi.
