New events module: a 500ms poller thread scans every enumerated device
and produces two read-only event streams:
- /scheme/pci/aer — uncorrectable (NonFatal) and correctable AER status
from the PCIe AER extended capability, emitted as
'severity=<level> device=<bdf> raw=...' lines and W1C-cleared
- /scheme/pci/pciehp — Slot Status events from hot-plug-capable ports
(presence detect, DLL state, attention button, MRL sensor, power
fault), emitted as 'kind=<event> device=<bdf>' lines and W1C-cleared
Events accumulate in capped in-memory logs (64 lines) served by the
scheme; device strings use the scheme dir-name format
(0000--00--1f.2) so driver-manager's route_to_driver matches bound
paths. The Pcie handle is now Arc-shared with the poller. Extended
capabilities need ECAM; on PCI 3.0 fallback machines the scanners
gracefully produce nothing. This wires driver-manager's previously
inert unified event listener to real producers.
