install-grub.sh now searches both recipes/core/bootloader/target and
local/recipes/core/bootloader/target for the Redox bootloader artifact.
The WIP grub recipe (recipes/wip/services/grub) is now a full directory
symlink to local/recipes/core/grub instead of just recipe.toml, ensuring
COOKBOOK_RECIPE resolves to a directory that contains grub.cfg. This also
eliminates the duplicate recipe warning from the cookbook.
The GRUB recipe now fails hard (exit 1) if grub.cfg is missing instead of
just warning.

The script now reads the Redox bootloader from the cookbook's bootloader
package output instead of extracting it from the ESP. This makes it
idempotent — previously, rerunning after GRUB install would copy GRUB
itself into EFI/REDBEAR/redbear.efi because ESP's BOOTX64.EFI was GRUB.

fat_tool.py provides zero-dependency FAT32 manipulation (ls, mkdir,
cp-in, cp-out) using only Python stdlib struct/os. install-grub.sh uses
it to extract the existing Redox bootloader from ESP, install GRUB as
the primary boot manager, and set up the chainload configuration.
