feat(web): surface QEMU logs in-page and enable guest-error diagnostics

Browse Source 
Add a log panel that captures QEMU stdout/stderr, route serial to stdio, and
pass -d guest_errors,unimp so device warnings (e.g. the m25p80 Read-ID gap that
stalls CrossPoint boot) are visible in the browser. Read the framebuffer via
HEAPU8 to match the validated node path.
