feat(palette): add Sublime Text as a consumer

Two outputs, not one. The colour scheme themes the editor pane and tracks
the wallpaper accent; the theme themes the UI chrome and sits on the
scheme's fixed accent, because Sublime reads a theme once per window and a
moving accent would leave open windows disagreeing with new ones.

The colour scheme costs no new roles. Its scopes map onto the sixteen ANSI
slots every scheme already declares, so all nine satisfy it and the
identical-role-set selftest passes untouched.

The theme is an override layered over Material Behave rather than a theme
of its own: that theme hardcodes 419 rules of [r,g,b] literals with no
variables, so the chrome surfaces are restated and its geometry, icons and
animations are inherited. It installs under the name of the theme it
overrides, because Sublime merges .sublime-theme files by filename with
Packages/User last; under its own name it would never apply. It also has
to follow Material Behave's material_theme_contrast_mode block and carry
no settings gate, or contrast mode wins.

The accent is replaced by matching the variable's current value rather
than a placeholder: install.sh copies the file out of the repo, so after
the first wallpaper change there is no placeholder left to substitute.
udt-accent --selftest now covers that it stays idempotent.
