The canonical colors.toml keys are now background/foreground, including
all permutations (dark_background, darker_background, lighter_background,
dark_foreground, light_foreground, bright_foreground). The old short
names are gone entirely, not kept as aliases; legacy alacritty-generated
themes still resolve through the ANSI color0/color7 fallback.
Theme files are also regrouped: accent/selection/muted first, then the
backgrounds, then the foregrounds, then the named colors.

* Make color0 distinct from background/foreground
The majority of themes have color0 available as a subtle offset from
the background. For flexoki-light, because color0 matched foreground, it
wasn't subtle, and would cause invisible text when used as a background
color (e.g., in text editor rulers). For vantablack, ethereal,
hackerman, and white, color0 matched background and would cause
invisible text when a theme wanted text to be de-emphasized.
This patch makes it consistently a subtle offset from background.
* Make helix selection theme colors more subtle
Helix is more usable if the selection background is subtle. This is
primarily because of [[1]], which makes a bright selection like we had
before often make the foreground text unreadable in the picker preview.
