No visible text cursor in Agent View input field on Windows

Environment

• Claude Code 2.1.173
• Windows 11 Pro (Build 26200), PowerShell 5.1
• Reproduced in both Windows Terminal and IntelliJ IDEA's integrated terminal

Steps to reproduce

1. Run claude agents to open the Agent View
2. Focus the dispatch input field at the bottom and type

Expected
A visible text cursor in the input field (as in the regular claude REPL, where the cursor shows correctly in the same terminals).

Actual
No cursor is visible anywhere while typing. Typed text appears, but there is no indication of the caret position.

Notes
The regular claude REPL shows the cursor fine in the same terminals, so this seems specific to the Agent View's fullscreen TUI rendering on Windows.
