On Omarchy the tray's StatusNotifierItem is always registered, so a user
who had magpie in the bar's tray and turned on Bar icon got the widget
beside it: two magpies. Wails has no Hide on Linux (a no-op), so the item
now says Status "Passive" while the widget is in (set through Wails' own
properties, as the tooltip is, with NewStatus sent), and "Active" again once
it is taken out. Omarchy's Tray.qml leaves Passive items out of both its
pinned row and drawer (bucket()), as waybar's tray does; Omarchy itself
hides Dropbox's tray item when its Dropbox widget is in the bar. The status
is set when the app starts (from whether the widget is in) and whenever
Settings' Bar icon adds or removes it (onBarIcon), from what is in the bar
afterwards even if the omarchy command failed.
TestBarIconTellsTheTray (POST /api/omarchy/widget on, then off, with
stand-in omarchy commands) fails with the call taken out: "Bar icon on: the
tray was told [], want [true]"; passes with it, -race -count=10.
On the omarchy VM (Omarchy 4.0.4 shell): a test SNI item pinned in the bar
showed when Active, was gone within a second of Passive + NewStatus and
came back on Active. This build (go build -tags gtk3 on the VM, vet clean),
run in a sandbox HOME with MAGPIE_OMARCHY=1: with the widget's files in its
config the tray item's Status read "Passive" over busctl, without them
"Active". Not run on the VM: turning the switch at runtime (the route is
covered by the test). go test -race ./internal/gui ./internal/omarchy,
gofmt, vet, darwin/linux nogui/windows builds pass.
