[FEATURE] "showThinkingIndicator": false would suppress the interactive indicator completely

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

Current behavior:

• "thinking": false only hides thinking block content in the conversation
• The interactive "thinking… (esc to interrupt)" indicator still appears during processing
• No way to disable this indicator through settings

Additional context

Some users (especially those working in screen/tmux sessions or with slow terminals) would benefit from a cleaner, less dynamic output. This would complement the existing "animations": false setting.

Current settings reference: https://code.claude.com/docs/en/settings.md

Proposed Solution

Desired behavior:

• "showThinkingIndicator": false would suppress the interactive indicator completely
• Users who prefer minimal terminal output could work without the flickering
• The indicator would still be enabled by default for users who find it helpful

Alternative Solutions

1. Keep current behavior - but causes flickering for some users
2. Reduce thinking frequency - helps but doesn't solve the UI issue
3. Use a different interface - not ideal for CLI-focused workflows

Priority

Medium - Would be very helpful
