Ctrl-D unexpectedly terminates session instead of deleting characters in macOS

Description

When using Claude Code CLI on macOS, pressing Ctrl-D unexpectedly terminates the entire session instead of deleting characters forward as it normally would in standard macOS terminals.

Expected Behavior

Ctrl-D should delete the character at the cursor position (forward delete), matching standard macOS terminal behavior.

Current Behavior

Pressing Ctrl-D immediately terminates the Claude Code session, causing loss of context and requiring restart.

Environment Information

• OS: macOS 15.4.1 (Sequoia)
• Terminal: xterm-256color (Node.js based terminal emulator)
• Claude Code version: 0.2.107 (Claude Code)
• Shell: zsh

Additional Information

This behavior is disruptive to the normal workflow as many macOS users rely on Ctrl-D for forward deletion. The termination happens without warning or confirmation, potentially causing loss of work.

Steps to Reproduce

1. Start Claude Code CLI with claude command
2. Begin typing a prompt
3. Position cursor within the text
4. Press Ctrl-D
5. Observe that the session terminates instead of deleting a character

This seems to be a regression from the fix applied in #960. It also impacts platform:linux

Can confirm there is a regression here recently.
