JetBrains Rider plugin incompatible with latest Claude Code version

Description

The Claude Code plugin for JetBrains Rider is not compatible with the newest Claude Code version. IDE detection fails even when the plugin is installed and enabled.

Environment

• IDE: JetBrains Rider (latest version)
• OS: Windows
• Claude Code: Latest version (installed via npm/brew)

Steps to Reproduce

1. Install Claude Code plugin in Rider (Settings → Plugins → Marketplace)
2. Ensure plugin is enabled
3. Restart Rider
4. Run claude from Rider's integrated terminal
5. Run /ide command

Expected Behavior

Claude Code should detect Rider as the active IDE and enable IDE integration features.

Actual Behavior

IDE detection fails. The /ide command does not recognize Rider.

Additional Context

• Plugin is installed and enabled (verified in Settings → Plugins)
• Rider has been restarted after plugin installation
• Claude is in PATH and runs correctly from integrated terminal
• claude doctor does not show Rider as a detected IDE

Possible Cause

The plugin may need to be updated to support breaking changes in the latest Claude Code version's IDE detection mechanism.
