lib/index
Moved all function-specific docs from `docs/lib/index.md` into RFC145 doc-comments. Added `lib.nixvim.lua.toLuaObject` to hold the public docs and serve as a stable impl of `toLua'` in case we decide to change its defaults.
Move heading to `pages.nix` page title.
user-guide/helpers.md
lib/index.md
