[BUG] Claude Code modifies PhpStorm terminal settings despite optionAsMetaKeyInstalled: true

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

When running Claude Code inside PhpStorm's integrated terminal, it automatically changes the terminal setting useOptionAsMetaKey to true in PhpStorm's configuration file
(~/Library/Application Support/JetBrains/PhpStorm2024.3/options/terminal.xml).
This happens even though ~/.claude.json already contains:
"optionAsMetaKeyInstalled": true

What Should Happen?

Claude Code should not modify IDE terminal settings, especially when optionAsMetaKeyInstalled flag is already set to true.
