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.

-# vim: ft=cfg
-#
-# This is the configuration file of "rifle", ranger's file executor/opener.
-# Each line consists of conditions and a command.  For each line the conditions
-# are checked and if they are met, the respective command is run.
-#
-# Syntax:
-#   <condition1> , <condition2> , ... = command
-#
-# The command can contain these environment variables:
-#   $1-$9 | The n-th selected file
-#   $@    | All selected files
-#
-# If you use the special command "ask", rifle will ask you what program to run.
-#
-# Prefixing a condition with "!" will negate its result.
-# These conditions are currently supported:
-#   match <regexp> | The regexp matches $1
-#   ext <regexp>   | The regexp matches the extension of $1
-#   mime <regexp>  | The regexp matches the mime type of $1
-#   name <regexp>  | The regexp matches the basename of $1
-#   path <regexp>  | The regexp matches the absolute path of $1
-#   has <program>  | The program is installed (i.e. located in $PATH)
-#   env <variable> | The environment variable "variable" is non-empty
-#   file           | $1 is a file
-#   directory      | $1 is a directory
-#   number <n>     | change the number of this command to n
-#   terminal       | stdin, stderr and stdout are connected to a terminal
-#   X              | $DISPLAY is not empty (i.e. Xorg runs)
-#
-# There are also pseudo-conditions which have a "side effect":
-#   flag <flags>  | Change how the program is run. See below.
-#   label <label> | Assign a label or name to the command so it can
-#                 | be started with :open_with <label> in ranger
-#                 | or `rifle -p <label>` in the standalone executable.
-#   else          | Always true.
-#
-# Flags are single characters which slightly transform the command:
-#   f | Fork the program, make it run in the background.
-#     |   New command = setsid $command >& /dev/null &
-#   r | Execute the command with root permissions
-#     |   New command = sudo $command
-#   t | Run the program in a new terminal.  If $TERMCMD is not defined,
-#     | rifle will attempt to extract it from $TERM.
-#     |   New command = $TERMCMD -e $command
-# Note: The "New command" serves only as an illustration, the exact
-# implementation may differ.
-# Note: When using rifle in ranger, there is an additional flag "c" for
-# only running the current file even if you have marked multiple files.
