[BUG] Right-click paste still broken in Claude Code terminal on ChromeOS Crostini (regression, still present as of 2.1.220)

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet (see #68620, which covers the same bug but was auto-closed by the stale bot with no fix)
• [x] This is a single bug report
• [x] I am using the latest version of Claude Code

What's Wrong?

Right-click paste does not work inside the Claude Code TUI on ChromeOS Crostini (Linux container). It works fine in a plain terminal session in the same environment, so the terminal/OS-level right-click-paste plumbing is functioning — the issue is isolated to Claude Code's own input handling.

ChromeOS Terminal's "Mouse right clicks paste content" setting is enabled (Settings > Keyboard & mouse), and this does not resolve it.

This duplicates #68620, which was auto-closed by the stale-bot for inactivity without any actual fix or maintainer response.

What Should Happen?

Right-click should paste clipboard content into the Claude Code prompt, matching behavior in a plain terminal on the same Crostini setup.

Steps to Reproduce

1. Open the ChromeOS Terminal app (Crostini/Linux container)
2. Confirm right-click paste works in a plain shell (e.g. cat or bash)
3. Run claude to start Claude Code
4. Copy some text, then right-click inside the Claude Code prompt to paste
5. Nothing is pasted

Is this a regression?

Yes — this worked in a previous version, per the original report in #68620.

Additional Information

Also tried Ctrl+Shift+V as an alternative — does not work either, consistent with what was reported in #68620. Filing this as a fresh report since #68620 was closed by the stale bot rather than resolved, and the issue is still present.
