redbear-info: pcid-spawner → driver-manager label; plan P2-1 done

redbear-info's integration check list still labeled the PCI spawner as
'pcid-spawner' and pointed at /usr/bin/pcid-spawner (deleted). Updated
to 'driver-manager' with /usr/bin/driver-manager and a note about
/scheme/driver-manager/bound. Plan v3.2 marks P2-1 done (pcid AER +
pciehp producers validated in QEMU).

+**P2-1 ✅ (2026-07-24): pcid produces AER + pciehp events.** A 500 ms
+poller thread in pcid scans every enumerated device: the AER scanner
+reads uncorrectable/correctable status from the PCIe AER extended
+capability (emits `severity=<level> device=<bdf>` lines, W1C-clears),
+the pciehp scanner reads Slot Status on hot-plug-capable ports (emits
+`kind=<event> device=<bdf>` lines for presence-detect, DLL state,
+attention button, MRL sensor, power fault, W1C-clears). Both streams
+are capped 64-line logs served read-only at `/scheme/pci/aer` and
+`/scheme/pci/pciehp`; device strings use the scheme dir-name format so
+`route_to_driver` matches bound paths. driver-manager's AER listener
+moved from the nonexistent `/scheme/acpi/aer` to `/scheme/pci/aer`.
+Extended capabilities need ECAM; fallback machines produce nothing
+gracefully. QEMU gate: poller running (6 devices, 500 ms), listener on
+the producer path, zero errors. MSI-based delivery remains the
+follow-up once pcid grows an IRQ path for AER/hotplug.

 Four runtime bugs found and fixed by the gate (none visible at compile
 grade — exactly why the runtime column exists):
