theme-gen: derive tmux and ghostty colours for any theme

`theme --set <mode> <name>` needs a tmux conf and a ghostty colour file that
alacritty-format themes do not provide, so such a name fell back to the
generic dark/light tmux colours and left ghostty unchanged, exiting 0.
bin/theme-gen reads a theme in alacritty .toml format (by alacritty-theme
checkout name or path) or Ghostty's bundled `palette = N=#hex` format, and
writes config/tmux/colors/<name>.conf and config/ghostty/colors/<name>, plus
config/alacritty/colors/<name>.toml for a ghostty-format source.

Generated with it: sonokai, solarized_osaka_night, kanagawabones and
dracula_plus_high_contrast, with nvim stand-ins for the three that have no
nvim port installed.

Parsed keys go through eval, so only plain section.key names and hex values
are accepted: a theme file could otherwise run commands.
