tui: question dialog "Type your own answer" input ignores Cmd+V paste #43241

Summary

In the question/selection dialog (the one where you pick from options or "Type your own answer"), the free-text "Type your own answer" input does not accept pasted text via Cmd+V. Pasting works fine in the main prompt input, so this appears specific to the question dialog's text entry.

Environment

• opencode version: 0.0.0-beta-17595 (beta channel; opencode --version on PATH reports 1.18.18)
• OS: Darwin 25.2.0 (darwin arm64) / macOS
• Terminal: WarpTerminal (TERM=xterm-256color, COLORTERM=truecolor)
• Shell: /bin/zsh
• Install/channel: beta
• Active plugins: claude-code-bounded.ts, claude-code-job-report.ts, claude-code-job-store.ts, claude-code-origin.ts, claude-code-runner-termination.ts, delegate-orchestration.ts, gsd-core.js, litellm-model-sync.ts, notify-macos.ts, session-context-tools.ts, @warp-dot-dev/opencode-warp, opencode-antigravity-auth@1.6.0, opencode-auto-continue, opencode-disabler@1.1.1, opencode-openai-codex-auth

Reproduction

1. Trigger a flow that shows the question dialog with selectable options and a "Type your own answer" free-text entry (e.g. the built-in question tool from a skill/agent).
2. Focus/select "Type your own answer" and type — typing works.
3. Attempt to paste text with Cmd+V.
4. Nothing is pasted into the field.

Expected Behavior

Cmd+V should paste the clipboard contents into the "Type your own answer" text input, same as it does in the main prompt input.

Actual Behavior

Nothing is pasted. Typed input works, but pasted input is ignored.

Additional Context

• Reproducible: consistently (every time).
• Paste works normally in other TUI inputs, including the main prompt, so the issue is specific to the question dialog's own-answer field.
• Terminal: Warp — but since paste works elsewhere in the TUI, this looks like the dialog input not handling the paste keybinding/event rather than a terminal issue.
