TUI renders incorrectly after some time - truncated lines, resize temporarily fixes

Bug: Question dialog duplicates options and truncates text

From screenshot (Build · Muse Spark 1.3 Contributor, Thought: 828ms, Asked 1 question):

• Question text split per line with left purple bars, hard to read:
  “El build en Vercel falla porque el JSON en GitHub ya tiene "pausado" pero el schema en GitHub (keystatic.config.tsx) no lo tiene. Localmente ya tenés el fix sin pushear. ¿Hago commit + push...?”
• Options rendered twice, overlapped:
  1. “Sí, pushear fix” appears twice
  2. “No, solo diagnóstico” appears twice
  3. “Type your own answer” appears twice
• Footer hints duplicated/overlapped: “↑↓ enter submit esc select dismiss” + “select dismiss” repeated.

Expected

• Each option rendered once
• Question body wrapped normally, no per-line truncation
• Single footer hint line

Repro

1. Build agent calls ask/question with 2 options + custom answer
2. Long Spanish question text (~300 chars)
3. Observe TUI dialog

Env

• opencode TUI, Build agent Muse Spark 1.3 Contributor
