Returning an empty `icon_name` in `tray_linux_ksni.rs` forces SNI
panels (e.g., KDE Plasma) to render the explicit `IconPixmap` data.
This prevents panels from incorrectly resolving the full-color app icon
from the system theme instead of the intended monochrome tray glyph.
Also updates `src-tauri/icons/icon-symbolic.svg` and regenerates
all `tray-dark-*.png` and `tray-light-*.png` assets.
Adds `static/logo.svg` as the main application logo.
The previous tray-light.png / tray-dark.png were 128x128 RGBA glyphs with a
black radial background. GNOME's StatusNotifierItem path expects monochrome
silhouettes around 22px base size and was rendering ours as the "three dots"
fallback.
Regenerate from icons/icon-symbolic.svg using Inkscape with a corrected
square viewBox (149 1 944 944, centred on the path bbox) and emit four
sizes per theme (22/32/44/64). decode_tray_icons() now returns Vec<Icon>
so ksni can offer the panel the best match for its bar height and HiDPI.

Apply the new matte-vinyl QBZ logo (Flathub-compliant: square canvas,
74% footprint, no baked shadows/gloss) across every icon asset: Tauri
standard sizes, Windows Store squares, Android icons and mipmaps,
static/, README, and the tray.
Ship two tray variants (black and white glyphs) and pick the right
one at runtime by reading GNOME color-scheme, GTK settings, and KDE
kdeglobals. Defaults to light-theme glyph when nothing matches.
Login screen: logo 80 -> 175 px with a subtle var(--text-muted)
drop-shadow using color-mix() for alpha, plus QBZ and "Qobuz(TM)
Player" under the icon. Update app.tagline i18n accordingly.
