refactor(cache): move the generated files to ~/.cache/udt

They lived in ~/.cache/wal because pywal owned that directory and udt-accent
was written alongside a pywal run. Nothing on this desktop invokes pywal any
more: the wal binary is unused, and udt-accent imports pywal.backends.colorz
as a quantisation library, which writes nothing. Sharing the cache only left
the ownership ambiguous.

colors.json is the one file that cannot move. pywalfox hardcodes
<cache>/wal/colors.json and honours only XDG_CACHE_HOME, which would relocate
every cache on the system, so udt-accent writes the real file to ~/.cache/udt
and install.sh symlinks the old path at it. ~/.cache/wal now holds that link
and nothing else.

Consumers repointed here: install.sh, udt-accent, launcher.rasi's @WPAPER@.
Outside the repo, wallp, Hyprland's look_and_feel.lua and quickshell's
shared/Theme.qml move with it.

 The extraction deliberately calls pywal's colorz backend directly rather than
 running `wal -i`, because `wal -i` rewrites the whole ~/.cache/wal directory
+(which this no longer writes to, but pywal still would)
 including the terminal's ANSI colors. See the design spec for why that matters.
