The tray drawer added complexity (drawer config, custom chevron module,
state-feedback CSS) for what amounts to a small visual refinement.
Removed in favour of the original always-visible tray. The mouse-battery
indicator was also removed from the bar.
Deletes:
- waybar/mouse-battery.sh + symlink + install.sh entry
- group/tray-drawer + custom/mouse-battery blocks in config.jsonc
- #custom-tray-arrow rules from style.css
- docs/superpowers/{specs,plans} for the drawer feature
