v0.4.0

Added

• CLI --sensors (and --sensors --json): compact live readout of temp, load, socket power, iGPU clock/temp, and memory clock
• CLI --info now shows a Driver line with the driver name, version, and status (or PCI direct access); same data under --info --json
• smu.read_pm_sensors(family) reads and decodes the PM table in one call, returning a PmSensors (or None). table.read_sensors(data, ver) decodes raw bytes you already have
• smu.module_status() returns one ModuleStatus verdict for the driver (ok, version, min_version, reason). Helpers: module_version(), module_version_ok(), is_available(), secure_boot_enabled(), driver_name()
• smu.ensure_backend(): like init() but returns the backend or None instead of raising
• smu.unavailable_reason(): the message explaining why the SMU can't be used, or None when it can
• smu.send_arg(family, name, value) sends one value to every mailbox the arg maps to, returning [(mailbox, opcode, status), ...]
• resolve(name, cpu_family, cpu_model) builds a CpuInfo from explicit values without reading /proc/cpuinfo
• runner.is_supported(family)
• All of the above are re-exported at the top level, so apps don't import from zenmaster.linux

Changed

• Linux now checks the ryzen_smu version (drv_version) and requires >= 0.1.7, with the installed version in the error
• Backend selection follows Secure Boot: off uses PCI direct access, on uses ryzen_smu. A loaded module is no longer preferred over PCI when Secure Boot is off
• On Windows, the driver is PawnIO with no version requirement, and Secure Boot does not apply
