feat(core): add batch methods to Suggest and update macro

Add `add_suggest()` and `add_suggest_with_description()` methods to
`Suggest` for ergonomic batch population of suggestion sets from
collections of strings.

Update the `suggest!` macro to use these new methods and accept
expressions beyond string literals for suggestion items.
