vasilito b13d4b30c3 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.

vasilito 4dc51bd61f driver-manager: v1.3 comprehensive D-phase implementation
Full implementation of the driver-manager migration's D-phase
(parallel development) per the v1.3 plan. The § 0.5 comprehensive
implementation principle is enforced by an automated audit-no-stubs
gate that returns 0 violations across 34 files. C-phase cutover remains
dormant and gated by ConditionPathExists until operator ratification.

redox-driver-core (28 unit + 5 integration tests):
- concurrent.rs: SMP-aware worker pool over std::thread::scope with a
  self-contained counting semaphore (Mutex+Condvar), preserving the
  existing serial enumerate() path
- dynid.rs: PciQuirkFlags-style runtime device-ID registration
  (add_dynid/remove_dynid/list_dynids), with the new DynidError type
- modern_technology.rs: concrete (non-stub) implementations of
  C-state/P-state advisors, IOMMU group registration, MSI-X vector
  proposal, NUMA node lookup
- driver.rs: Driver::on_error() trait method with ErrorSeverity and
  RecoveryAction types; default Driver::params() now provides
  universal enabled+priority fields instead of empty defaults
- manager.rs: DeviceManager::remove_device() authoritative unbind path,
  plus buses_iter / drivers_iter / bound_devices_snapshot /
  deferred_queue_snapshot accessors
- tests/dynid.rs: integration tests for the DeviceManager API

redox-driver-pci (3 tests, unchanged):
- pre-existing PciBus; no breakage

driver-manager (13 tests):
- Cargo.toml: adds redox-driver-sys path dep
- quirks.rs: integrates redox_driver_sys::pci::PciDeviceInfo +
  PciQuirkFlags — NEED_FIRMWARE defers probe, NO_MSIX/NO_MSI/
  FORCE_LEGACY_IRQ signal intx-fallback, DISABLE_ACCEL signals
  accel-disable
- config.rs: real SIGTERM-then-SIGKILL signal_then_collect for
  Driver::remove() (3s grace, 50ms poll, escalation); format coexistence
  loader accepting both [[drivers]] legacy and [[driver]] new formats
  with auto-detect; spawn_decision_gate() 5-signal committee
- hotplug.rs: poll reduced 2000ms → 250ms; exhaustive match arms
  with log lines (not silent _ => {})
- main.rs: 250ms hotplug poll, exhaustive match arms with log lines

redox-driver-sys quirks:
- dmi.rs: log instead of silent _ => {} catch-all

Driver manager policy package (redbear-driver-policy):
- /etc/driver-manager.d/00-blacklist.conf (4 driver blacklist entries)
- /etc/driver-manager.d/50-amdgpu.toml (AMD GPU driver policy)
- /etc/driver-manager.d/initfs.manifest (ordered initfs driver list)
- /etc/driver-manager.d/autoload.d/ntsync.conf (autoload ntsync module)
- /etc/driver-manager.d/README.md (explanation)
- recipe.toml: custom install script that stages into /etc/driver-manager.d/

Driver manager service files (in local/sources/base submodule):
- local/sources/base/init.d/00_driver-manager.service — dormant
  (oneshot_async, ConditionPathExists=!/etc/driver-manager.d/disabled)
- local/sources/base/init.initfs.d/40_driver-manager-initfs.service —
  dormant (oneshot, ConditionPathExists=!/etc/driver-manager.d/initfs-active)

Audit gate:
- local/scripts/driver-manager-audit-no-stubs.py: static analysis
  scanning 34 source files for stub macros (R1), empty catch-all
  match arms (R2), and DriverParams::default() stubs (R3). Returns
  0 violations at v1.3.
- local/scripts/driver-manager-audit-no-stubs.sh: thin wrapper
- local/scripts/test-driver-manager-no-stubs-qemu.sh: D4 gate — runs
  the audit plus cargo test on every crate, returns 0 iff both pass

Test scripts (C-phase scaffolding, dormant until C1):
- test-driver-manager-parity.sh (C1)
- test-driver-manager-active.sh (C3)
- test-driver-manager-initfs.sh (C2)
- test-driver-manager-hotplug.sh (D3)
- test-driver-manager-pm.sh (D2)
- test-driver-manager-cutover.sh (C4)

Docs:
- local/docs/DRIVER-MANAGER-MIGRATION-PLAN.md: v1.3 status table
  listing every D-phase item as Done
- local/docs/evidence/driver-manager/D5-AUDIT.md: capability-by-
  capability matrix + verbatim audit output
- local/docs/HARDWARE-VALIDATION-MATRIX.md: driver-manager rows
  added with v1.3 status
- local/AGENTS.md: PLANNING NOTES pointer updated to v1.3
- docs/README.md: Related Red Bear-local plans row updated to v1.3

Test totals: 49 tests across the three crates, all passing.
Audit totals: 0 violations across 34 files, all clean.

Note: local/sources/base service files (00_driver-manager.service and
40_driver-manager-initfs.service) live in a submodule and need a
separate commit there. They are NOT included in this commit.
