Instruction step loop + per-step peripheral tick

Priority 0 - Core Emulator Infrastructure / 0.1 Execution core: time, scheduling, determinism

As an emulator integrator, I want vemu's Instruction step loop + per-step peripheral tick to stay accurate, tested, and documented, so that I can keep depending on the actual execution engine.

Why it matters

The actual execution engine

Summary

Drives the machine: step CPU - > tick peripherals - > dispatch IRQs

Scope of work

Already implemented. Harden, broaden coverage, add tests and documentation for Instruction step loop + per-step peripheral tick. What it is: Drives the machine: step CPU - > tick peripherals - > dispatch IRQs. Why it matters: The actual execution engine.

Current state

Status: Fully implemented. Notes / evidence: vemu-cortex-m/src/machine.rs, vemu-cortex-a/src/machine_a53_64.rs - polling, not event-driven.
