chore: 1.5.0

KDE's own middle-click paste is turned off along with everything else. Inside a
Chromium application the flag already settles it - with autoscroll on, Blink
stops pasting the primary selection - but everywhere else on the desktop middle
click goes on pasting, which is the thing this program exists to get away from.

KWin has a switch for it on a Wayland session, where the paste is a protocol
the compositor either offers or does not, and that is what gets written. It is
true from the next login on. What the key said before is recorded, so disable
puts it back, and a key that already said no is left alone and never switched
back on. X11 has no such switch and nothing is written there.

Off under Settings for anyone who wants the paste kept.

 ## How it works
 
 Blink (the engine in Chromium, Electron, and CEF) already has autoscroll, but
-it's off on Linux because middle click does primary-selection paste there. This
-flag turns it on:
+it's off on Linux by default because middle click normally pastes the clipboard (??).
+This flag turns it on:
 
 --enable-blink-features=MiddleClickAutoscroll
 
 But doing that for every app is kinda bothersome and it also might break with updates.
 That's why I created this small tool to automate that.
 
-Browsers get the same thing asked for differently:
+Browsers get the same thing but this time without "blink":
 
 --enable-features=MiddleClickAutoscroll
 
-Both mean the same feature - Blink generates a matching feature name for each of
-its runtime flags - but the first one is on Chromium's list of flags worth
-warning about, so a browser started with it shows a yellow "unsupported
-command-line flag" bar over every page. The second one is not on that list, so
-there's no bar. It only works from Chromium 124 on, which is why apps that
-embed something older (Steam's CEF, older Electron) keep the first one - they
-have no such bar to begin with. Helium, which carries the feature under its own
-name, is asked for `HeliumMiddleClickAutoscroll` alongside it.
+But both do the same ¯\_(ツ)_/¯
 
 New apps are picked up by a systemd path unit that watches the
-relevant directories. Without systemd, `middleclick-autoscroll apply` does the
+relevant directories. If you hate systemd; `middleclick-autoscroll apply` does the
 same thing manually.
 
-## Steam
-
-Steam's web UI supports autoscroll but has no way to pass extra arguments to its
-helper, so the program patches the script that starts it. Steam checks its own
-files against its manifest - by size and timestamp - and reinstalls the whole
-client package over anything that differs, so the patch is written to look
-unchanged: the bytes the argument costs are taken back out of the script's
-comments and the timestamp is put back.
-
-If that can't be done - a script with no comments left to pay for the argument,
-or one this version doesn't recognise - nothing is written and Steam is left
-alone. A file of the wrong length costs the client package downloaded and
-installed again, and a Steam that quits at the end of it instead of coming up;
-no autoscroll in Steam is the smaller problem. Nothing is added to Steam's
-launcher entry or to the shortcuts it writes for games, and Steam keeps
-repairing its own installation.

+Inside a Chromium application the argument settles this on its own: with

+middle click goes on pasting, so the desktop's own switch for it is turned off

+What the key said before is recorded, and *disable* puts that back. A key that
