* feat(plugin): multi-line text input via ui.input-multiline
Adds host::input_multiline: a multi-line text dialog pre-filled with a
value, dismissed to none, confirmed with Cmd/Ctrl+Enter. Same rules as
input (command or event of a window, no capability, wait not charged).
Prompt::Input gains a multiline flag the frontend renders as a
textarea; the jobs fixture, SDK (wasm + mock), WIT and the plugin API
table are updated, and all plugin wasms rebuilt.
Fixes#1946
