feat: add minimal mode for reduced color palette

Add new `minimal` config option that provides a cleaner, more focused
  color scheme with fewer distinct colors:
  - Variables/constants: white
  - Functions/methods: blue
  - Types: aqua
  - Keywords/statements: gray
  - Operators: yellow
  - Brackets/punctuation: gray
  - Properties/members: violet
