[FEATURE] Add configuration option to exit with single Ctrl+D press

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, Claude Code requires pressing Ctrl+D twice to exit the interactive session. While this safety mechanism helps prevent accidental exits, it would be helpful to have a configuration option to allow exiting with a single Ctrl+D press for users who prefer this behavior.

Current Behavior:

• Ctrl+D must be pressed twice to exit
• This is hardcoded and not configurable

Proposed Solution

Requested Feature:
Add a configuration setting (e.g., in settings.json) such as:
{
"exitOnSingleEOF": true
}
