goal: Implement missing VM lifecycle operations (Update, Reset, Hotplug) and ChainFire state watch

  **Findings from T049 Audit:**
  - `vm_service.rs` TODOs: Update, Reset, Disk/NIC attachment/detachment.
  - "Implement VM watch via ChainFire watch" is pending.

  **Strategic Value:**
  - Required for production operations (resizing VMs, recovering stuck VMs, attaching volumes).
  - ChainFire watch is critical for multi-node state synchronization (HA).

acceptance:
  - VM Update (CPU/RAM) changes persisted and applied (next boot or live if supported)
  - VM Reset (Hard/Soft) functional
  - Disk/NIC hot-plug/unplug functional via QMP
  - PlasmaVMC servers watch ChainFire for state changes (external coordination)

steps:
  - step: S1
    name: VM Lifecycle Ops
    done: Implement Update and Reset APIs

  Depends on QMP capability of the underlying hypervisor (KVM/QEMU).
