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.

-##############################################################
-## This is the example bindings file. Copy it to            ##
-## $XDG_CONFIG_HOME/ncmpcpp/bindings or ~/.ncmpcpp/bindings ##
-## and set up your preferences.                             ##
-##############################################################
-##
-##### General rules #####
-##
-## 1) Because each action has runtime checks whether it's
-##    ok to run it, a few actions can be bound to one key.
-##    Actions will be bound in order given in configuration
-##    file. When a key is pressed, first action in order
-##    will test itself whether it's possible to run it. If
-##    test succeeds, action is executed and other actions
-##    bound to this key are ignored. If it doesn't, next
-##    action in order tests itself etc.
-##
-## 2) It's possible to bind more that one action at once
-##    to a key. It can be done using the following syntax:
-##
-##    def_key "key"
-##      action1
-##      action2
-##      ...
-##
-##    This creates a chain of actions. When such chain is
-##    executed, each action in chain is run until the end of
-##    chain is reached or one of its actions fails to execute
-##    due to its requirements not being met. If multiple actions
-##    and/or chains are bound to the same key, they will be
-##    consecutively run until one of them gets fully executed.
-##
-## 3) When ncmpcpp starts, bindings configuration file is
-##    parsed and then ncmpcpp provides "missing pieces"
-##    of default keybindings. If you want to disable some
-##    bindings, there is a special action called 'dummy'
-##    for that purpose. Eg. if you want to disable ability
-##    to crop playlists, you need to put the following
-##    into configuration file:
-##
-##    def_key "C"
-##      dummy
-##
-##    After that ncmpcpp will not bind any default action
-##    to this key.
-##
-## 4) To let you write simple macros, the following special
-##    actions are provided:
-##
-##    - push_character "character" - pushes given special
-##      character into input queue, so it will be immediately
-##      picked by ncmpcpp upon next call to readKey function.
-##      Accepted values: mouse, up, down, page_up, page_down,
-##      home, end, space, enter, insert, delete, left, right,
-##      tab, ctrl-a, ctrl-b, ..., ctrl-z, ctrl-[, ctrl-\\,
-##      ctrl-], ctrl-^, ctrl-_, f1, f2, ..., f12, backspace.
-##      In addition, most of these names can be prefixed with
-##      alt-/ctrl-/shift- to be recognized with the appropriate
-##      modifier key(s).
-##
-##    - push_characters "string" - pushes given string into
-##      input queue.
-##
-##    - require_runnable "action" - checks whether given action
-##      is runnable and fails if it isn't. This is especially
-##      useful when mixed with previous two functions. Consider
-##      the following macro definition:
-##
-##      def_key "key"
-##        push_characters "custom_filter"
-##        apply_filter
-##
-##      If apply_filter can't be currently run, we end up with
-##      sequence of characters in input queue which will be
-##      treated just as we typed them. This may lead to unexpected
-##      results (in this case 'c' will most likely clear current
-##      playlist, 'u' will trigger database update, 's' will stop
-##      playback etc.). To prevent such thing from happening, we
-##      need to change above definition to this one:
-##
-##      def_key "key"
-##        require_runnable "apply_filter"
-##        push_characters "custom_filter"
-##        apply_filter
-##
-##      Here, first we test whether apply_filter can be actually run
-##      before we stuff characters into input queue, so if condition
-##      is not met, whole chain is aborted and we're fine.
-##
-##    - require_screen "screen" - checks whether given screen is
-##      currently active. accepted values: browser, clock, help,
-##      media_library, outputs, playlist, playlist_editor,
-##      search_engine, tag_editor, visualizer, last_fm, lyrics,
-##      selected_items_adder, server_info, song_info,
-##      sort_playlist_dialog, tiny_tag_editor.
-##
-##    - run_external_command "command" - runs given command using
-##      system() function.
-##
-##    - run_external_console_command "command" - runs given console
-##      command using system() function.
-##
-##
-## 5) In addition to binding to a key, you can also bind actions
-##    or chains of actions to a command. If it comes to commands,
-##    syntax is very similar to defining keys. Here goes example
-##    definition of a command:
-##
-##      def_command "quit" [deferred]
-##        stop
-##        quit
-##
-##    If you execute the above command (which can be done by
-##    invoking action execute_command, typing 'quit' and pressing
-##    enter), ncmpcpp will stop the player and then quit. Note the
-##    presence of word 'deferred' enclosed in square brackets. It
-##    tells ncmpcpp to wait for confirmation (ie. pressing enter)
-##    after you typed quit. Instead of 'deferred', 'immediate'
-##    could be used. Then ncmpcpp will not wait for confirmation
-##    (enter) and will execute the command the moment it sees it.
-##
-##    Note: while command chains are executed, internal environment
-##    update (which includes current window refresh and mpd status
-##    update) is not performed for performance reasons. However, it
-##    may be desirable to do so in some situration. Therefore it's
-##    possible to invoke by hand by performing 'update enviroment'
-##    action.
-##
-## Note: There is a difference between:
-##
-##         def_key "key"
-##           action1
-##
-##         def_key "key"
-##           action2
-##
-##       and
-##
-##         def_key "key"
-##           action1
-##           action2
-##
-##      First one binds two single actions to the same key whilst
-##      second one defines a chain of actions. The behavior of
-##      these two is different and is described in (1) and (2).
-##
-## Note: Function def_key accepts non-ascii characters.
