driver-manager: v1.9 — QEMU-functional test scripts + MODALIAS + Linux pci_device_id parsing

Seventh-round integrations of the driver-manager migration's D-phase.
This round makes the 6 test scripts actually run QEMU via qemu-login-expect.py,
adds a MODALIAS scheme endpoint for operator queries, and ports
Linux's pci_device_id parsing so Linux drivers can be loaded with
least effort.

Test scripts (6, all functional now):
- test-driver-manager-parity.sh (C1 dual-mode observation): runs QEMU with
  redbear-mini live.iso, expects driver-manager and pcid-spawner to both
  bind the same 17 drivers. Exits 0 on PASS, 1 on FAIL, 0 on SKIP
  (QEMU not available).
- test-driver-manager-active.sh (C3 active): QEMU with driver-manager active,
  verifies all 17 drivers bind and scheme:driver-params is present.
- test-driver-manager-initfs.sh (C2 initfs): QEMU virtio-blkd boot,
  verifies storage drivers come up before redoxfs mounts.
- test-driver-manager-hotplug.sh (D3 hotplug): QEMU with QMP socket,
  verifies PCIe hotplug detection (sub-200ms latency).
- test-driver-manager-pm.sh (D2 runtime PM): QEMU with driver-manager
  bound drivers, verifies suspend/resume callbacks fire.
- test-driver-manager-cutover.sh (C4 production): QEMU 3-reboot bound-set
  identity check.

modalias.rs (NEW):
- compute_modalias(info) returns a MODALIAS string in Linux's
  pci_uevent format (pci:v0000VVVVd0000DDDDsv0000SSSSsd0000UUUUbcCCccSScciiII).
- compute_match_modalias(matches) computes per-match MODALIAS for
  a driver's match_table.

linux_loader.rs (NEW):
- parse_linux_id_table(path) reads a Linux driver's pci_device_id
  table from C source and returns a Vec<LinuxPciId>.
- parse_linux_id_table_from_source(source) parses from a string.
- to_driver_match(id) converts a LinuxPciId to redox_driver_core::r#match::DriverMatch.
- Handles named vendor constants (PCI_VENDOR_ID_INTEL, INTEL, AMD, NVIDIA,
  QCOM, REALTEK, BROADCOM, AQUANTIA, MARVELL, AMPERE, MICROSOFT, SONY,
  TI, RENESAS, NOVELL, SIS, VIATECH, HYGON).
- Linux class field is a packed 3-byte value (base<<16|subclass<<8|prog_if)
  and is decoded back into separate class/subclass/prog_if fields.

scheme.rs:
- Added /modalias endpoint. Write MODALIAS string, get back the
  matching driver name (used by operators for manual driver selection).

main.rs:
- Declared modalias.rs and linux_loader.rs.

Docs:
- DRIVER-MANAGER-MIGRATION-PLAN.md v1.9 status table
- D5-AUDIT.md v1.9 update
- AGENTS.md + docs/README.md pointers to v1.9

Test totals: 39 tests across 4 crates, all passing.
