Plan mode missing from mode cycle on Windows - Shift+Tab only toggles to auto-accept

What's Wrong?

After updating to Claude Code 2.1.3, Plan mode is no longer accessible via keyboard shortcut on Windows. Pressing Shift+Tab only cycles between Edit mode and Auto-accept mode. Plan mode is completely missing from the cycle.
The ? help screen confirms this — it only shows "shift + tab to auto-accept edits" with no mention of Plan mode.
Plan mode was previously accessible via Alt+M or Ctrl+M in earlier versions on Windows.
Environment Info

Platform: Anthropic API (Claude Max)
Claude CLI version: 2.1.3
Operating System: Windows 11
Terminal: Windows Terminal (CMD inside WT), also tested in standalone CMD

Steps to Reproduce

Install Claude Code 2.1.3 on Windows
Launch claude in Windows Terminal (CMD) or standalone CMD
Press Shift+Tab — cycles to auto-accept only
Press Shift+Tab again — cycles back to edit mode
Press ? to view shortcuts — Plan mode not listed

Expected Behavior
Shift+Tab should cycle through: Edit mode → Auto-accept → Plan mode → Edit mode
Actual Behavior
Shift+Tab only cycles: Edit mode → Auto-accept → Edit mode
Plan mode is inaccessible via any keyboard shortcut.
Additional Context
The changelog for 2.1.x mentions "Windows: native installation uses shift+tab as shortcut for mode switching, instead of alt+m" — but Plan mode appears to have been dropped from the cycle entirely.

What Should Happen?

Enter plan mode!!! This is the most important feature I use. MUST be able to enter mid converstaion like I have for months. Can I rollback to a prior claude code cli version?
