A shell that comes back, a recording you can hear, a layout you can see

Quickshell segfaulted mid-session -- a Qt image-teardown bug, three cores in
the journal -- and the desktop stayed bar-less until a person noticed and
knew what to type, because the shell ran as a bare compositor child and
panama-crash-watch's report had no notification server left to arrive on.
The shell is now panama-quickshell.service, started per-session by
autostart.lua like every other Panama unit and never enabled globally:
Restart=on-failure turns the same crash into a two-second flicker, verified
by sending the running shell a real SIGSEGV and watching it return, and the
crash report now lands because the restarted shell is serving the bus by the
time the watcher looks. The two contracts that restart the shell learned to
do it through the unit, or the unit's own restart races them with a second
shell.

Recordings can hear: a recorderAudio preference -- none by default, GNOME's
default too, because a screencast that silently captured the microphone is an
incident -- adds system audio or the microphone through PulseAudio's
@DEFAULT_*@ aliases, so the capture follows whatever device Sound settings
has chosen.

The bar shows the active keyboard layout whenever more than one is
configured, mapped from xkb's own registry (evdev.lst) because deriving a
code from a description guesses wrong immediately -- "German" is de, not ge
-- and updated live from Hyprland's activelayout event. One layout, no
indicator, which is GNOME's behavior too.

And presentation mode: Caffeine plus Do Not Disturb as one quick-settings
tile, restoring both exactly as found -- the half you forget to arm before
plugging into a projector is the one that fires a message preview onto the
big screen.
