feat: ACPI S3 suspend-to-RAM + battery status queries (18 patches)

P3-4: ACPI S3 sleep — suspend_to_ram() method reads _S3 AML,
writes PM1a_CNT with SLEEP_EN + SLP_TYPa. Gated to x86/x86_64.
Applies after shutdown hardening for correct context.

P3-6: ACPI battery — read_battery_status() queries _BST,
read_battery_info() queries _BIF. Returns capacity/voltage data.

18/18 patches. base + base-initfs build.
