Type Alias AutocompleteSuggestionOptions

EXPERIMENTAL: Automatically fill required leaf nodes recursively upon triggering code completion events.

• [x] fills required nodes
• [x] automatically expands relay-style node/edge fields
• [ ] automatically jumps to first required argument field
  • then, continues to prompt for required argument fields
  • (fixing this will make it non-experimental)
  • when it runs out of arguments, or you choose { as a completion option that appears when all required arguments are supplied, the argument selection closes ) and the leaf field expands again { \n| }
