fix(archsetup): correct invalid sudo syntax in yay installation

Fixed critical bug at line 336 that blocked all AUR package installations.
Changed invalid 'sudo -u $username -D $build_dir' to proper 'cd $build_dir && sudo -u $username' pattern.

Also updated TODO.org:
- Marked yay bug task as DONE
- Created "Resolved Tasks" section
- Moved completed task to archive with resolution notes
