Create grub-install and grub-mkconfig scripts in local/scripts/ that match GNU GRUB CLI conventions for users migrating from Linux. Support standard switches: --target, --efi-directory, --bootloader-id, --removable, -o/--output, --verbose, --help, --version. Unsupported Linux options are accepted and ignored for script compatibility. Also fix ESP FAT type: force FAT32 in both with_whole_disk and with_whole_disk_ext4 (UEFI spec requires FAT32, fatfs auto-selects FAT16 for partitions under 32 MiB). Fix --write-bootloader to export GRUB EFI in GRUB mode. Fix CLI example in GRUB plan. Update AGENTS.md and GRUB-INTEGRATION-PLAN.md with Linux-compatible CLI docs.
