refactor(dotfiles): rename system/ to common/ and remove unused configs

Rename dotfiles/system to dotfiles/common for clarity - indicates
shared dotfiles used across all desktop environments (DWM, Hyprland).

Removed config directories for uninstalled applications:
- ghostty (using different terminal)
- lf (using ranger instead)
- mopidy (using mpd instead)
- nitrogen (X11-only, obsolete for Wayland)
- pychess (not installed)
- JetBrains (not installed via archsetup)
- youtube-dl (using yt-dlp with different config location)

Kept audacious config for potential future use.

Updated all references in archsetup, CLAUDE.md, todo.org, and
validation.sh.

-# zsh-ls-colors
-
-![Demo screenshot](https://raw.githubusercontent.com/xPMo/zsh-ls-colors/image/demo.png)
-
-A zsh library to use `LS_COLORS` in scripts or other plugins.
-
-For a simple demo, see the `demo` script in this repo.
-
-For more advanced usage,
-instructions are located at top of the source files for `from-mode` and `from-name`.
-If a use case isn't adequately covered,
-please open an issue!
-
-## Using zsh-ls-colors in a plugin
-
-You can use this as a submodule or a subtree.
-
-### submodule:
-
-```sh
-# Add (only once)
-git submodule add git://github.com/xPMo/zsh-ls-colors.git ls-colors
-git commit -m 'Add ls-colors as submodule'
-
-# Update
-cd ls-colors
-git fetch
-git checkout origin/master
-cd ..
-git commit ls-colors -m 'Update ls-colors to latest'
-```
-
-### Subtree:
-
-```sh
-# Initial add
-git subtree add --prefix=ls-colors/ --squash -m 'Add ls-colors as a subtree' \
-	git://github.com/xPMo/zsh-ls-colors.git master
-
-# Update
-git subtree pull --prefix=ls-colors/ --squash -m 'Update ls-colors to latest' \
-	git://github.com/xPMo/zsh-ls-colors.git master 
-
-
-# Or, after adding a remote:
-git remote add ls-colors git://github.com/xPMo/zsh-ls-colors.git
-
-# Initial add
-git subtree add --prefix=ls-colors/ --squash -m 'Add ls-colors as a subtree' ls-colors master
-
-# Update
-git subtree pull --prefix=ls-colors/ --squash -m 'Update ls-colors to latest' ls-colors master 
-```
-
-### Function namespacing
-
-Since functions are a public namespace,
-this plugin allows you to customize the preifix for your plugin:
-
-```zsh
-# load functions as my-lscolors::{init,match-by,from-name,from-mode}
-source ${0:h}/ls-colors/ls-colors.zsh my-lscolors
-```
-
-### Parameter namespacing
-
-While indirect parameter expansion exists with `${(P)var}`,
-it doesn't play nicely with array parameters.
-
-There are multiple strategies to prevent unnecessary re-parsing:
-
-```zsh
-# Call once when loading.
-# Pollutes global namespace but prevents re-parsing
-ls-color::init
-```
-
-```zsh
-# Don't call init at all and only use ::match-by.
-# Doesn't pollute global namespace but reparses LS_COLORS on every call
-ls-color::match-by $file lstat
-```
-
-```zsh
-# Initialize within a scope with local parameters.
-# Best for not polluting global namespace when multiple filenames need to be parsed.
-(){
-	local -A namecolors modecolors
-	ls-color::init
-
-	for arg; do
-		...
-	done
-}
-```
-
-```zsh
-# Serialize:
-typeset -g LS_COLORS_CACHE_FILE=$(mktemp)
-(){
-	local -A namecolors modecolors
-	ls-color::init
-	typeset -p modecolors namecolors >| $LS_COLORS_CACHE_FILE
-	zcompile $LS_COLORS_CACHE_FILE
-}
-
-my-function(){
-	local -A namecolors modecolors
-	source $LS_COLORS_CACHE_FILE
-
-	...
-}
-```
