State diffing

As an emulator integrator, I want vemu's State diffing to stay accurate, tested, and documented, so that I can keep depending on observe mode/security/SP changes.

Why it matters

CPU-only diffs are insufficient for embedded triage; expand toward a full-system diff

Summary

Pre/post CPU-state delta - > trace

Scope of work

Expand state diffing from a CPU delta to a full-system diff. What it is: registers, RAM ranges, MMIO and selected peripherals. Why it matters: observe mode/security/SP and peripheral changes.

Current state

Status: Fully implemented. Notes / evidence: machine_m33.rs emit_state_diff.
