chore: remove all X11/Xorg configs and references

Removed:
- home/.config/{X11,bspwm,sxhkd,polybar,rofi,dunst,sxiv,sx,alacritty}
- meta/{x-base,x-de,x-extra} metapackages
- barscripts/ (polybar GPU scripts)
- nvim sxhkdrc ftplugin and treesitter parser

Updated:
- mimeapps.list: sxiv → imv
- ghostty config: bspwm → sway comment
- .zshrc: alacritty → xterm-ghostty in TERM check
- .zprofile: removed bspwm from comment
- copilot-instructions.md: removed X11 references

 - `etc/` and `etc2/` contain system-level configs (`/etc/` targets) — systemd units, pacman hooks, sysctl tunables, kernel module loading.
 - `meta/` contains Arch Linux PKGBUILDs that bundle groups of packages into metapackages (e.g. `sommerfeld-base`, `sommerfeld-dev`). Each subdirectory is a standalone PKGBUILD recipe with a `.SRCINFO` and pre-built `.pkg.tar.zst` artifacts.
 - `lists/` holds keymap files (e.g. `caps2esc.map`).
-- `barscripts/` has polybar status bar scripts (GPU stats) — legacy X11, kept for reference.
+- `barscripts/` is unused (legacy X11 polybar scripts, removed).
 - `firefox/` contains Firefox hardening overrides and custom CSS.
 - `create-efi.sh` is an interactive EFI boot entry creation script using `efibootmgr`.

Uses vanilla sway defaults for all standard WM operations with personal keybinds layered on top for media, volume, screenshots, lock screen, notifications, and display mode switching. The status bar is waybar (`home/.config/waybar/`), notifications via mako (`home/.config/mako/config`), and the launcher is fuzzel (`home/.config/fuzzel/fuzzel.ini`). Old X11 configs (bspwm, sxhkd, polybar, rofi, dunst) are kept in the repo for reference but are no longer active.

 - **`doas` over `sudo`**: The system uses `doas` as the privilege escalation tool; `sudo` is aliased to `doas`.
 - **GPG-signed commits**: All git commits and tags are signed. The GPG agent also handles SSH authentication.
 - **Secrets via `pass`**: API keys and tokens are stored in the `pass` password manager and sourced into env vars at shell init, never hardcoded.
-- **Host-specific branching in `.zprofile`**: Hardware-dependent config (GPU drivers, display scaling) is conditioned on `$HOST` (hostnames: `hercules`, `halley2`).
 - **EditorConfig**: LF line endings, UTF-8, final newlines, trimmed trailing whitespace. Lua uses 2-space indentation with 80-char line limit. Makefiles use tabs.
