zed 0.108.1

In addition to fixing a panic, this makes it slightly more convenient to
re-open disconnected channel notes views. I didn't make it automatic,
but it will at least replace the previous, disconnected view.

Release Notes:

- Fixed a crash that sometimes occurred when following someone with a
disconnected channel notes view open.
