fix(shikane): detect silent deadlocks; re-apply profile on sway reload

watchdog: covers both observed deadlock flavours -- the loud one that repeats
"Received invalid input AtomicChangeDone at state Discarded", and the silent
one that logs nothing and just never leaves VariantInProgress.

shikane-recover-on-reload.sh (new, previously referenced by sway/config but
never committed): shikanectl reload -> sleep 2 -> watchdog check, falling
back to a service restart when reload cannot recover.

clamshell-mode.sh: documents why the laptop panel is no longer enabled
unconditionally on lid-open, which raced shikane's "External Display" profile
(eDP-1 disabled by design) and produced "Atomic commit failed: Device or
resource busy" churn.
