  • syslogDump now outputs all five diagnostic sections (Fault Info,
    CPU Registers, Process Info, System Info, Call Stack) to serial,
    matching the on-screen BSOD content
  • panic() detects if the crash occurred in the gfxd process and
    falls back to rendering the BSOD directly to the VESA framebuffer
    via driver.video text drawing, bypassing LVGL entirely
  • Add DrawChar, DrawString, DrawHex, DrawInt to driver.video for
    8x16 bitmap font rendering directly to the framebuffer
  • Export SHOULD_CRASH flag from svc.gfxd interface so test commands
    can trigger a deliberate gfxd crash
  • Add app.divzero with DIV0, PF, and CRASHGFXD test commands
  • Update doc/src/core/core.panic.md and doc/src/driver/video/driver.video.md
