Skip-sudo fixes for run_once_40 and run_once_20

Three real bugs caught during the bit-cachyos deploy:

1. wl-clipboard false-positive: 'command -v wl-clipboard' returns
   nothing because the package ships wl-copy/wl-paste, not a
   'wl-clipboard' binary. Sudo pacman was being called every apply
   even though wl-clipboard is installed. Fix: declare -A PKG_BIN
   map in the script.

2. omp segfault aborts the whole bootstrap: on rye, 'bun add -g
   @oh-my-pi/pi-coding-agent' segfaults (Pi undervoltage, see
   pitfall #30). The 'set -e' caused the whole run_once_20 to abort
   before getting to neovim/oh-my-zsh/zshrc etc. Fix: wrap the bun
   add in a subshell with error tolerance, log a warning, keep going.

3. rorclar/sourdough reference cleanup: removed the old chaotic-aur
   comment which mentioned the wrong sudo pattern (now fixed in the
   other run_once scripts).

Re-applied on bit, miche, byte, kaiser, crouton (rye skipped because
of the undervoltage hardware issue).
