CLI startup splash incorrectly says 'PyCharm plugin' for all JetBrains IDEs

The CLI startup splash displays this message:

↑ Install the PyCharm plugin from the JetBrains Marketplace

This is confusing when using IntelliJ IDEA or other JetBrains IDEs. Since the same Claude Code plugin works across all JetBrains IDEs (IntelliJ, PyCharm, WebStorm, GoLand, etc.), the message should either:

1. Detect which JetBrains IDE is being used and customize the message (e.g., "Install the IntelliJ plugin")
2. Use generic wording like "Install the JetBrains plugin"

Environment:

• IDE: IntelliJ IDEA
• OS: Linux

This is a minor UX issue that creates unnecessary confusion for users of non-PyCharm JetBrains IDEs.
