Adds pawlethwd, a native C++ system_ext daemon (coredomain) that detects peripherals, checks the hardware update catalog (ota.php?mode=hardware), verifies payloads, and flashes firmware via authorized handler plugins. - daemon/: manifest parse, libcurl HTTP + sha256, sysfs USB detection, catalog client, dlopen handler registry (fixed path + ABI + allowlist), state persistence, orchestration engine, AIDL service, main. - aidl/: IPawletHardwareUpdate (getComponents/getPendingUpdates/checkNow/...). - include/pawlet/hwh_abi.h: stable C plugin ABI. - handlers/usbdfu/: libpawlethwh_usbdfu.so, DFU 1.1 download over libusb. - sepolicy/: pawlethwd domain, pawlet_hw_data_file, service type. - schemas/, etc/supported_hardware.default.json, README design doc. - hwupdate.mk wires packages + ro.pawlet.hardware.manifest + sepolicy dir; inherited from config/common.mk. Trust: a server-named installer handler is honored only if allowlisted in the immutable supported_hardware.json, maps to a fixed dm-verity-protected .so path, is ABI/id-checked, and every payload is sha256-verified before a handler runs.
