Keep Wi-Fi visible when hiding other menu bar icons

Hiding pushed Wi-Fi off along with the third-party app icons. Tune the
spacer boundary to sit just left of Wi-Fi so apps disappear while the
Apple Wi-Fi, Spotlight, Clock, Battery and Control Center icons remain.

 What it can and cannot hide:
 
-- It hides **other third-party apps' icons** (and can also catch some Apple
-  items such as Wi-Fi).
-- It **cannot** hide **Spotlight, Clock, Battery, or Control Center**. macOS
-  reserves the far right of the menu bar for those, and a third-party app cannot
-  place its item to their right, so there is nothing to push them with. (This is
-  the same limit Bartender and Ice hit; they cover the area with their own
-  overlay bar instead.)
+- It hides **other third-party apps' icons** (cmux, Kapture, WireGuard, input
+  source, Now Playing, …) so only your apps' icons leave the bar.
+- It **keeps Wi-Fi, Spotlight, Clock, Battery and Control Center**. The spacer's
+  boundary is tuned (preferred position 250) to fall just left of Wi-Fi, so the
+  Apple items on the right stay visible. macOS reserves that far-right area: a
+  third-party item can never be placed to the right of it, so those icons cannot
+  be pushed away even in principle. (Bartender and Ice hit the same wall and
+  cover the area with their own overlay bar instead.)
 - Newly launched apps are placed to the left of the spacer, so they are hidden
   automatically.
+- Advanced: set `defaults write dev.tzgyn.simpletopbar debug.spacerPos -float <n>`
+  to move the boundary (larger = keep more icons; > ~400 starts leaking app
+  icons back into the bar).
