Search from the launcher, and give the touchpad something to do

Four things a Hyprland desktop can do that this one was not.

Searching from the launcher needed no launcher work at all: Vicinae already
models it, so this is a script command with one percent-encoded argument. Make
it the fallback command and anything typed that matches nothing else offers to
search it. Bangs come free -- they are a property of where the query is sent,
not of the launcher -- so !yt reaches YouTube without a line of bang parsing.

Suggestions could not be a script command. They need a view that reacts as you
type, which is an extension: TypeScript, compiled, querying the same endpoint
Firefox's address bar uses. It debounces, and aborts the request in flight on
every keystroke -- typing is faster than the network, and an older answer
landing after a newer one leaves the list describing a query that is no longer
on screen. A bang skips suggestions entirely, because Google has no useful
guesses about "!yt".

The engine is now written down twice, once in each. The contract pins that they
agree, since searching from the fallback and searching from the suggestions
reaching different places is the kind of wrong that looks fine.

Gestures mirror GNOME: three fingers sideways for workspaces, up for the
overview, down to dismiss it. Open and close rather than toggle both ways --
toggling means swiping up from an open overview closes it, which is not what the
fingers meant. Hyprland reads gesture registrations at startup so they cannot be
a setting, but distance and direction can be, and are.

Window swallowing is off by default and a preference like every other misc
setting here. A terminal that vanishes when you did not ask for it is confusing
rather than broken, which is worse.

+  A gear, because a settings icon has to be recognizable at 48px in a dock
+  before it is anything else - but rendered in the Prism identity rather than
+  the flat monochrome symbolic icon this replaces. Blue leads into orchid, the
+  same pair that marks the focused window, the active workspace, and the
+  hairline along every glass surface.

+  strokes; at dock size the strokes merged into the ring and it read as an X.
