Subject: [PATCH] fix(core): seed multiline prompt with initialValue

The multiline prompt accepted `initialValue` but never seeded the editor
with it, unlike the text prompt, so passing it had no effect. Forward
`initialValue` (falling back to `initialUserInput`) to the base Prompt so
the value is present when the prompt opens.

Closes #566

+Fix `multiline` prompt ignoring `initialValue`. The editor is now seeded with `initialValue` (falling back to `initialUserInput`) when the prompt opens, matching the `text` prompt.
