replace ad hoc driver loading with a proper driver manager, new DDK, new PnP manager with device matching, asynchronous startup, resource ownership and removal, add shared PCI capability helpers, replace typed, rigid services with a proper service manager, implement proper system shutdown and restart, shutting down unloads drivers and shuts down services, add simple power button, remove heavyweight boot self-tests and SMP stress runs, add monotonic timestamps to kernel debug output, fruitless USB and PS/2 fixes, make test builds opt in.

Load order:
`drivers.ini` should load `lwip.sys` before NIC drivers so the provider is
ready when the NIC registers. The kernel also supports provider-after-device
registration, but provider-first keeps boot logs cleaner.
`drivers.ini` v2 uses `class.network-stack` with `after=network-adapter`.
NIC modules initialize first; lwIP attaches to already registered adapters.
The stack also initializes normally when no physical NIC is present.
