ComfyUI Base 2.9.1: the forwarded ports say why they are forwarded

TUNNEL_SERVICES carries 9199 and 11434 next to ComfyUI's 8188 and JupyterLab's 8888, and the comment beside
them explained only the per-alias offset (a collision measured on two live machines), never why those two
ports were in the list at all. Read cold they look like leftovers, and this session came close to deleting
11434 as one.

They are not. The base runs no metrics exporter and no inference server, but a PACKAGE may run one on the
machine and talk to it on loopback, which is the shape a package takes when its whole point is that nothing
leaves the box. Removing the forward would break such a package silently, from the Mac side, with nothing in
the log to say why.

Said in both places now: beside the list, and in the handbook where the tunnel is described.
