isMobile() returns true on Linux desktop with touchscreen #284
Description
On Linux, navigator.maxTouchPoints > 0 can be true on desktop machines with a touchscreen. isMobile() interprets this as mobile, halving the SplatPager page pool (256 → 128 pages). The existing Windows guard correctly handles this case for Windows touch devices — the same guard should cover Linux, since Linux is always a desktop OS regardless of touch capability.
