andrew ab869119cc Fix Qt compatibility and VM script docs

Updates desktop shell and application code for cross-Qt compatibility: uses begin/endFilterChange for Qt 6.10+, gates LayerShell usage to Qt < 6.5, and adds include handling for generated QML type registration files so nebula-shell builds reliably. Also fixes qInfo size formatting casts and updates README commands to invoke run-sway-vm.sh via `sh` for more portable execution.

Compositor

Sway is the temporary Wayland compositor while Nebula Desktop is developed. Configuration lives in sway/nebula-sway.conf.

Sway currently provides:

Wayland compositor
application window management
XWayland
input and the pointer cursor
output handling

Nebula provides the visible shell (Qt Quick/QML via LayerShellQt). The Sway config must not enable a Sway bar.

A custom Nebula compositor is a later milestone. Do not treat this Sway setup as the final architecture.

Development session

From the NebulaOS repository root:

sway -c compositor/sway/nebula-sway.conf

Recommended on the Ubuntu VMware VM (repo-root cd, cursor environment, software cursors):

sh compositor/sway/dev/run-sway-vm.sh

Sway then autostarts Nebula Desktop through scripts/run-nebula-vm.sh.

Skip shell autostart:

NEBULA_SHELL_AUTOSTART=0 sh compositor/sway/dev/run-sway-vm.sh

Output / resolution

The development config uses scale 1 and requests 1920x1080 when that mode is advertised. If it is not, Sway keeps the preferred mode. This is a VM convenience, not a production requirement.

swaymsg -t get_outputs
swaymsg output <name> mode 1920x1080
swaymsg output <name> scale 1

Cursor

seat * xcursor_theme Adwaita 24
XCURSOR_THEME=Adwaita
XCURSOR_SIZE=24

Requires adwaita-icon-theme. A Nebula-branded cursor theme is a later task.

WLR_NO_HARDWARE_CURSORS=1 is VMware-specific and is set by run-sway-vm.sh, not by production session files.

Emergency shortcuts

Shortcut	Action
Super+Enter	open Foot
Super+Shift+E	exit Sway
Super+Shift+C	reload Sway config

Normal application launching is done from the Nebula launcher, not these shortcuts.

Rendering

scripts/run-nebula-vm.sh sets QT_QUICK_BACKEND=software for the VMware guest GPU. Production nebula-shell must not set that variable.
