Martino Ferrari f3d68cfdd4 feat: an app icon in colour and symbolic form, validated at build time
Both are drawn to the GNOME HIG: a 128px instrument face that leaves its
margins, carries one 4px front profile for depth and no gradients or shadows,
and a 16px symbolic reduction of the same metaphor in fills only. The colour
icon strokes its sine because it is never recoloured; the symbolic one cannot.

Every file in the manifest now preprocesses through xmllint, because a
malformed SVG is the one icon failure no runtime check can see: librsvg refuses
the file while the name still resolves, so the icon draws nothing and
has_icon() says it is fine.

# --- libadwaita: the shortcut overview ---------------------------------------
# GTK4's own `GtkShortcutsWindow` is deprecated as of 4.18 and libadwaita's
# `AdwShortcutsDialog` (1.8) is its replacement, so the overview is built from the
# platform widget rather than from a hand-rolled grid. This is the only thing libadwaita
# is used for; `adw_init()` is called for it, which also means the app picks up
# libadwaita's stylesheet.

# because udpscope is run straight out of the build tree and has no install step: a
# search path would have to be located at runtime, and the failure mode of not locating
# it is a silent missing-image placeholder.
