chore: remove unused exports and dead css.d.ts

- camelCase removed entirely (never imported anywhere)
- PATH_STYLE_ATTRS, ChildEntry, createChildRegisterHandler made private
  (used only internally within their modules)
- src/types/css.d.ts deleted (leftover from an earlier
  approach — no .css imports exist in the source)
