Summary

• Add multiple: true support to question prompts and request schema.
• Standardize replies to answers: string[][] (always arrays; no union types).
• Update TUI question flow to toggle selections with enter and improve Other editing/unselect behavior.
• Regenerate OpenAPI + JS SDK types for the new schema.

Notes

• Single-select questions still auto-submit when only one question is asked.
• Multi-select questions (including single-question multi-select) use the Confirm tab.
