archlinux/archiso — reverse-engineered prompt

Build me a command line project for Arch Linux that can create custom bootable Arch installation media. I want it to include ready made profile templates, one very small baseline profile and one release style profile like the official monthly installer, and let me copy a profile, edit its files, then build an ISO from it.

The main script should take a work folder, an output folder, and a profile folder, then produce install media that can boot on both BIOS and UEFI systems. It should also be able to make bootstrap tar images and the needed netboot files if the profile asks for them.

Please include a helper script that can boot a finished ISO in QEMU for testing, with an option for UEFI. Add clear help output, man page friendly docs, examples, and a Makefile install target. Keep it mostly shell based and make it lintable with shellcheck. Look up current Arch docs online if you need to.
