0.3.2 moved the Quickshell entries into ui/boot, and the 0.3.4-1 package here does not install them, so flea exits with "the shell config is missing" (thisisgm/flea#216). This installs ui/boot with its Commons and Ui links, bumps to 0.3.5, and ships the pacman hook that notes on removal what flea --default and --picker left behind.
