Michael Chus 00bb2fdace feat(audit): 1.3 — CPU collector (dmidecode type 4, microcode)
- cpu.go: collectCPUs(), parseCPUs(), parseCPUSection()
- splitDMISections(): splits multi-section dmidecode output generically
- parseFieldLines(): reusable key→value parser for DMI sections
- parseCPUStatus(): Populated/Unpopulated → OK/WARNING/EMPTY/UNKNOWN
- parseSocketIndex(): CPU0/Processor 1/Socket 2 → integer
- cleanManufacturer(): strips (R), Corporation, Inc. suffixes
- parseMHz(), parseInt(): field value parsers
- Serial fallback: <board_serial>-CPU-<socket> when DMI serial absent
- readMicrocode(): /sys/devices/system/cpu/cpu0/microcode/version
- cpu_test.go: dual-socket, unpopulated skipped, status, socket, manufacturer, MHz
