Real deps, not placeholder: pawlet_x86_64_pc-kernel (was never actually
wired in despite the kernel workstream being marked done), plus
device/mainline/common + hardware/mainline/common +
external/linux-firmware-mainline + prebuilts/bootmgr +
device/virt/virt-common (lineage-23.2 throughout, matching the kernel's
branch) — LineageOS's own real foundation for basic_x86_64_pc, covering
the GRUB bootloader chain and most of real-hardware HAL bring-up.
