Wait for v86 emulator-loaded before restoring state (#367)

Browse Source 
The 500ms setTimeout raced against v86's async wasm/BIOS/hda load. When
loading exceeded 500ms (cold cache, Gatekeeper scan on packaged apps),
restore_state ran on an uninitialized CPU, threw, was silently caught,
and the VM cold-booted from default-state.bin instead of resuming the
user's session.
