chore: add stylua/selene/prettier config files

Add minimal config for the upcoming fmt/lint recipes:

- .stylua.toml: stylua-specific knobs only; indent/line-length/eol
  continue to come from .editorconfig (stylua reads it natively).
- selene.toml + nvim.yml: lua51 base plus a 'vim' global so neovim
  config files don't get flagged as undefined.
- .prettierrc.json: double quotes, trailing commas, 80-col, preserve
  prose wrap (avoid reflowing markdown).

All four ignored by chezmoi so they stay repo-only.
