refactor(platform): migrate device mechanics to the neutral facade - #1344

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The refactor centralizes device enumeration and classification, but the current revision can omit Windows port metadata or later COM ports after malformed registry data, misses a supported macOS usbserial naming form, and contains a documentation link that may fail warnings-as-errors checks.

/dev/cu.usbserial without a suffix is not classified.
Lines 89-90 require usbserial- or usbserial.. Older FTDI drivers on macOS publish the node as /dev/cu.usbserial with no suffix. That name returns None today. A single starts_with("usbserial") covers all three forms and stays inside the bridge class.
The fallback on None keeps this safe, so this is a small coverage gap and not a defect.

property() passes the buffer size in u16 units, but the API expects bytes.
SetupDiGetDeviceRegistryPropertyW takes PropertyBufferSize in bytes. Line 770 passes property_buf.len() as u32, which is 260 for [u16; MAX_PATH], while the buffer holds 520 bytes. Values longer than 129 characters are reported as insufficient-buffer and property() returns None, so SPDRP_MFG and SPDRP_FRIENDLYNAME silently drop for long strings. property_from_info at Line 1006 already passes (buffer.len() * 2) as u32. Align the two.
The under-report is memory-safe, so this affects metadata completeness only.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A single unexpected SERIALCOMM value stops the whole enumeration.
Line 1137 uses break. RegEnumValueW is indexed by idx, so one entry with a non-REG_SZ type or an oversized value ends the loop and drops every later COM port in HKLM\HARDWARE\DEVICEMAP\SERIALCOMM. Use continue for the per-value validation failures and keep break only for the RegEnumValueW call failure.

Phase 7 of the platform-boundary refactor (#1313). All native serial/USB/PnP mechanics move out of fbuild-serial into fbuild-core's per-OS platform tree behind the neutral platform::device facade: - platform/windows/device.rs: the SetupAPI serial enumeration fork (#962), USB problem-device and Pico reset-interface enumeration, the WinUsb BOOTSEL reset, and the CfgMgr32 PnP recovery primitives (#1148/#1152) - platform/linux/device.rs: sysfs kernel-driver classification (#895) plus the portable serialport enumeration delegate - platform/macos/device.rs: device-node-naming classification plus the same portable delegate - fbuild-serial keeps the caller-facing policy layer: PortHealth flattening, DetectedPort, the sysfs health enrichment, and the recovery ladder over a PlatformPnpBackend that delegates to the facade (fails closed off Windows exactly as before) - fbuild-serial drops its windows-sys dependency; fbuild-core gains the serialport delegate dep and the Windows Devices/Registry features - ban_direct_serialport allowlist gains the three new facade files (#1313 justification); boundary ledgers regenerated (95 -> 57 rows) No behavior change: all public paths (ports::available_ports, UsbProblemDevice/UsbResetInterface re-exports, port_class shim, usb_recovery entry points) keep their names and signatures.

Phase 7 of the platform-boundary refactor (#1306 plan, #1313).
Moves the last of fbuild-serial's host mechanics behind the neutral
fbuild_core::platform::devicefacade. After this PR,fbuild-serialcontains no#[cfg(target_os)]attributes and no direct SetupAPI/CfgMgr32/WinUsb calls — it is a pure consumer of the facade, matching phases 1–6.What moves
ports.rsimp) →platform/windows/device.rs: SetupAPI port fork (Ports+Modem GUIDs, SERIALCOMM fold-in), HWID/identity parsing, kernel-driver detection stub (serial: detect CDC native USB from OS port name when VID/PID is unknown #895 deferred).platform/windows/usb_pnp.rs:present_usb_problem_devices, Pico BOOTSEL reset interface (WinUsb control transfer), PnP inspect/reenumerate/restart with post-op polling. (Split from enumeration to stay under the 1000-LOC file gate; both files are ~700 LOC.)device.rsinto per-OSusb_pnp.rsso every OS tree has the same two-module shape and the facade stays cfg-free.platform/linux/device.rs; macOS devnode naming inplatform/macos/device.rs.platform/device.rs:DevNodeObservation,KernelDriverClass,UsbSerialIdentityFacts,SerialPortTypeFacts(collapsed toUsb | Unknown— upstream's PCI/Bluetooth variants are unit variants carrying no facts),UsbProblemDevice,UsbResetInterface,UsbPnpDevice.port_class.rsis now a re-export + one delegating fn;usb_recovery.rskeeps only the trait ladder and backend wiring;ports.rsmaps facts ⇄serialport::SerialPortInfo.windows-sysdependency moves from fbuild-serial to fbuild-core; serialport allowlist gains the three new facade files (the blessed wrapper's new home).Boundary accounting
