[Bug] Right-click paste duplicates text in WSL 2 terminal since v2.1.143

Description

Since v2.1.143, right-clicking to paste in Claude Code always pastes the clipboard content twice. The regression persists in the latest release (v2.1.146). Ctrl+V continues to paste correctly as a single insertion, so the duplication is specific to the right-click paste path.

Environment

• Windows 11, WSL 2, VS Code integrated terminal
• Claude Code v2.1.146 (broke in v2.1.143; v2.1.142 and earlier were fine)

Repro

1. Copy any text.
2. In Claude Code running in VS Code's integrated terminal (WSL), right-click to paste.
3. Text is pasted twice.

Notes

• Ctrl + V pastes correctly (once).
• Right-click paste works correctly in Windows Terminal (WSL).
• Issue is specific to right-click paste in VS Code's integrated terminal.

Workaround is Ctrl + V, but right-click paste is frequent enough that this is disruptive.

Environment Info

• Platform: linux
• Terminal: vscode
• Version: 2.1.146
