* fix: add bg/fg aliases for theme color resolution Themes define bg/fg but the template system expects background/foreground. The fallback chain only checked color0/color7, leaving background/foreground empty for themes using bg/fg naming. * Complete legacy theme palette compatibility --------- Co-authored-by: David Heinemeier Hansson <david@hey.com>
