feat: migrate from archiso to artools — are you threatening me in SKECHERS?!

Strip out archiso (airootfs, efiboot, syslinux, mkarchiso, prepare.sh,
Dockerfile, mirrorlist, profiledef.sh, packages.x86_64, reset.sh,
run_before_squashfs.sh) and adopt artools buildiso with full antergos
iso-profiles. Bitch, you NEED therapy.

Are you threatening me?
- 154 files changed, 2804 insertions, 7352 deletions
- buildiso wrapper + iso-profiles/antergos/ (profile.yaml, root-overlay,
  live-overlay) + iso-profiles/common/common.yaml
- pacman.conf.d/iso-x86_64.conf with antergos-pkgs repo first

...Are you THREATENING me in SKECHERS?!
- Calamares offline + online module dirs, antergos-next branding
- componentName must match dir or Branding.cpp goes full T-square
- calamares before calamares-branding-antergos-next so --overwrite='*'
  wins correctly. YOU'RE ON YOUR FOURTH WIFE RIGHT NOW-
- calamares-next.desktop in live-overlay (/usr/share + /etc/skel/Desktop)
- netinstall.yaml bundled. No remote deps. Kill that bitch (Cnchi).

What fuckin' college would care if you drew some bullshit picture
about your feelings?
- CI: artixlinux/artixlinux:base container, install artools, buildiso -p
  antergos, IA upload with collection=open_source_software. Class is in
  session. Maybe I should grow 40 feet! Then you'd REALLY like me!
- IA: mediatype=software keeps us out of Community Texts jail. The
  question is; what's this stick gonna do?

It's honestly super humbling, when the trashiest repo you know;
probably coked out of its mind... says the most thoughtful thing
you've done in years.
- README.md rewritten with Artix/OpenRC/KDE badges, build instructions,
  migration notes. Nice SpongeBob impression. ...Nice SpongeBob impression.
- AGENTS.md updated (identity ritual, gotchas, commands, repo layout)
- Restore LICENSE, NOTICES, APOLOGY.txt, CHANGELOG.md from git history.
  Some files you just don't let die. No matter what, you NEVER use that
  N-word! (...should've said nothing.)
- .gitignore: work/ iso/ out/. Go work at Starbucks with your little apron.

So laugh all you want. Forget about me all you want. But at least
I'll be gorgeous forever. Mother, I'm in the SquashFS now.

+# To support multiple instances of this module,
+# some strings are configurable and translatable here.
+# Sub-keys under *label* are used for the user interface.
+#  - *sidebar* This is the name of the module in the progress-tree / sidebar
+#   in Calamares.
+#  - *title* This is displayed above the list of packages.
+# If no *sidebar* values are provided, defaults to "Package selection"
+# and existing translations. If no *title* values are provided, no string
+# is displayed.
+#
+# Translations are handled through `[ll]` notation, much like in
+# `.desktop` files. The string associated with `key[ll]` is used for
+# *key* when when the language *ll* (language-code, like *nl* or *en_GB*
+# or *ja*) is used.
+#
+# The following strings are **already** known to Calamares and can be
+# listed here in *untranslated* form (e.g. as value of *sidebar*)
+# without bothering with the translations: they are picked up from
+# the regular translation framework:
+#  - "Package selection"
+#  - "Office software"
+#  - "Office package"

+#  - "Browser package"
