vm.go (1529 LOC) splits into vm_create, vm_lifecycle, vm_set, vm_stats, vm_disk, vm_authsync; firecracker/DNS/helpers stay in vm.go. guest_sessions.go (1266 LOC) splits into session_controller, session_lifecycle, session_attach, session_stream; scripts and helpers stay in guest_sessions.go. Mechanical move only. No behavior change. Adds doc.go and ARCHITECTURE.md capturing subsystem map and current lock ordering as the baseline for the upcoming subsystem extraction.
