[Bug] IDE detection fails when running Claude Code in JetBrains Rider terminal

Bug Description
On windows native install, when I run Claude Code inside Jetbrains Rider's terminal (with the plugin installed) the IDE is not detected. If I run Claude Code in an external terminal, it detects Rider just fine. Also as you can see below, it detects the terminal as pycharm, which is incorrect.

Environment Info

• Platform: win32
• Terminal: pycharm
• Version: 2.1.23
• Feedback ID: 0f198640-c009-4e0d-87e1-29e5a0ae5657
