Subject: [PATCH] fix: guard openInEditor when inspector is unavailable

When the component inspector is not initialized, calling openInEditor through the Vite plugin path throws because __VUE_INSPECTOR__ is missing.

Guard the call and log a clear warning instead, so DevTools does not crash in this state.
