- Add /grub/{hwaddr} route for serving GRUB configuration files,
replacing the shim handler with a config-based approach
- Add short URL aliases: 'system' for overlay-system, 'runtime' for
overlay-runtime, and 'grub' stage in parser
- Add 'grub' to status stage tracking in request handling
- Add comprehensive test coverage for EFI, GRUB, initramfs, iPXE,
overlay, and provision handlers (efi_test.go, grub_test.go,
initramfs_test.go, ipxe_test.go, overlay_test.go)
- Expand existing parser and provision tests
- Remove shim.go (functionality folded into grub.go)
- Add userdocs/server/routes.rst documenting all warewulfd HTTP routes
