What's Wrong?

When using the PyCharm plugin with multiple Claude Code terminal tabs open, pressing Ctrl+Alt+K to insert a source code reference exhibits incorrect behavior:

• The code reference is inserted into ALL open Claude terminal tabs
• Focus jumps to the first Claude terminal tab

What Should Happen?

• The code reference should be inserted only into the currently focused Claude terminal
• Focus should remain on that terminal tab

Steps to Reproduce

1. Open PyCharm with the Claude Code plugin installed
2. Open two or more Claude Code terminal tabs
3. Focus on a terminal tab that is NOT the first one
4. Press Ctrl+Alt+K to insert a code reference
