Ctrl+V paste not working on Windows 11 TUI

[jabing]

Description

Bug Description

On Windows 11, Ctrl+V does not paste text in the TUI prompt. The issue occurs in Windows Terminal, cmd, and PowerShell.

Plugins Used

None

OpenCode Version

1.1.53

Steps to Reproduce

1. Install opencode on Windows 11
2. Start TUI: opencode
3. Copy some text to clipboard
4. Press Ctrl+V in the prompt
5. Expected text to be pasted, but nothing happens

Root Cause

The current implementation only handles image paste via Ctrl+V and relies on terminal bracketed paste for text content. However, Windows terminals may not properly send bracketed paste sequences.

Environment

• OS: Windows 11
• Terminal: Windows Terminal / cmd / PowerShell

Proposed Fix

Directly read clipboard and insert text when Ctrl+V is pressed, instead of relying on terminal bracketed paste.

Fixed in this pr #13871

Root Cause

The onKeyDown handler for input_paste (Ctrl+V) in prompt/index.tsx calls Clipboard.read(), which successfully reads both images and text from the clipboard. However, only the image/* case was handled — for text content, the handler fell through expecting the terminal to emit a bracketed paste sequence. Windows Terminal, cmd, and PowerShell do not reliably send bracketed paste sequences for Ctrl+V key presses, causing text paste to silently fail.

Fix

clipboard.ts: Added Clipboard.readText() — a dedicated text reader that uses clipboardy.read() and normalizes CRLF/CR line endings to LF.
