Generate Lupine's app themes from colors.toml

Rename the palette keys to the canonical background/foreground names the
resolver actually reads. The short bg/fg spellings were never aliased, so
every derived key was silently falling back.

Fill in the orange and brown slots too. Lupine is a deliberately cool,
near-monochrome blue palette, so both stay in family rather than
introducing warm hues the theme never had.

Drop neovim.lua and vscode.json. They pinned third-party extensions that
had to be installed separately; the generated templates cover both from
colors.toml alone.
