A window's layout changed.

`layout` and `visibleLayout` carry whatever tmux hands this connection: on
3.8+ that is JSON, the same wire form a snapshot's `window_layout` reports
(the connection requests it on attach); before 3.8 tmux has only the
classic layout string, on both sides. Either is an opaque token to compare
for equality, not a grammar to parse.
