The previous fix attached a 32x32 @2x representation to the 16x16 PNG,
which only covers 100% and 200% scale factors. Users on 125/150/175/
250%+ still got a blurry tray icon because Windows had to resample from
one of those two sizes.
Ship a proper multi-size tray-icon.ico (16, 20, 24, 32, 40, 48, 64) and
point the Windows tray loader at it. Windows picks the closest size per
DPI scale on its own, so no addRepresentation / resize juggling is
needed. Linux keeps the existing PNG + @2x path; macOS is unchanged.
Also add scripts/generate-tray-ico.py so the .ico can be regenerated
from public/icon-win.png whenever the source artwork changes.
