- Convert 21 absolute-path symlinks into YADR to relative paths
(e.g. .vimrc -> .yadr/vimrc), so they resolve correctly under
any user's $HOME after a standard YADR install.
- .fehbg: replace hardcoded background path with $HOME-based one
- .gtk-bookmarks: remove (trivially personal; GTK regenerates)
- .themes/*/index.theme: drop BackgroundImage= lines pointing at
personal image files that other users won't have.
- .xscreensaver: scrub username from header comment.
- .irssi/config: generic dcc_download_path.
Tracks shell configs (zsh/bash), vim, tmux, irssi, fonts, themes,
and ~/.local/bin scripts. Sensitive files (.ssh, .gnupg, history,
credentials) and large app data are excluded via .gitignore.
