Clarify build targets, add GRUB live configs, clean up docs

Consolidate compile target naming (redbear-live, redbear-grub-live-full,
etc.), add config/redbear-grub-live-full.toml, make redbear-live-full-grub
a legacy alias, update build-iso.sh to support all GRUB live targets, and
sync AGENTS.md/README.md build command documentation.
