Support blinking cursor in Claude Code CLI

Feature Request

The cursor in Claude Code CLI does not blink, even though the terminal (iTerm2, Terminal.app) has blinking cursor enabled.

Claude Code uses its own TUI render engine which overrides the terminal's cursor settings. It would be great if Claude Code respected the terminal's cursor blink setting, or had its own option to enable a blinking cursor.

This would improve the visual experience, especially for users who prefer a blinking cursor for better visibility.

Expected behavior

Cursor should blink in the Claude Code input area, matching the terminal's cursor blink settings.

Current behavior

Cursor is static/non-blinking regardless of terminal settings.

Environment

• macOS
• iTerm2 + Terminal.app
• Claude Code CLI (latest)
