feat(palette): generate every themed config from one scheme

Colours were written down five times: rofi's palette.rasi, the waybar theme,
the kitty theme, the conky and dunst templates, and a MACCHIATO dict inside
udt-accent. Changing scheme meant finding all five, and they had already
drifted: the active waybar theme was Macchiato while theme.css next to it was
Mocha, and nothing imported the latter.

Now a scheme is two files. palette/<scheme>.conf holds the colours under the
scheme's own names, and palette/roles-<scheme>.conf says what each is for.
palette/roles.conf is one `scheme =` line selecting the pair. bin/udt-palette
renders that into each consumer's syntax and install.sh runs it first.

The role map is per-scheme rather than shared because the palettes are
genuinely different shapes: Nord has no `base`, Dracula no `surface0`, and
forcing Catppuccin's names onto them would have meant either renaming their
colours or inventing values. A role names a palette colour with two optional
modifiers, `name/75` for alpha and `name*50` for brightness. The second exists
because GTK's shade() has no palette name to point at.

Ships macchiato, tokyo-night, nord and dracula. --selftest resolves every role
in every scheme and asserts they define the same set, so a scheme that cannot
satisfy a consumer fails at install rather than when someone switches to it.

Verified against the live configs: all 46 waybar colours resolve identically to
the previously active theme including its alpha() and shade() derivations, the
kitty theme is colour-for-colour identical, and the rofi palette has the same
26 values. Generated files are gitignored; switching scheme and switching back
reproduces the originals.
