[Bug] UI Freeze when starting Eclipse IDE

Environment

• OS: Windows 11
• Eclipse Version: 4.40
• Plugin Version: 0.20.0.202607100822 and also 0.21.0.202608060743

Describe the bug
UI Freeze when starting the Eclipse IDE.

My assumption is that the method com.microsoft.copilot.eclipse.ui.preferences.LanguageServerSettingManager.updateMcpToolsStatus () goes through all the projects in the workspace and it does so in the UI thread.

Pay attention to the Hits column on the right: the actual numbers are not real but the fact that there is a steep increase from 1 to 40+ shows that there is a for-loop somewhere that creates this issue. My bet is on the method com.microsoft.copilot.eclipse.core.utils.WorkspaceUtils.listTopLevelProjects ().

To Reproduce
Open the Eclipse IDE

Expected behavior
The UI shouldn't freeze, it should remain responsive

Additional context
We downgraded to version 0.19.0.202606240339 and we hope that this version doesn't have the issue. I will report back in this issue if 0.19.x also has this problem.

Start by tracing com.microsoft.copilot.eclipse.ui.preferences.LanguageServerSettingManager.updateMcpToolsStatus() and com.microsoft.copilot.eclipse.core.utils.WorkspaceUtils.listTopLevelProjects(), focusing on whether workspace traversal runs on the UI thread. Reproduce by opening Eclipse with the reported plugin versions and confirm that startup remains responsive without the observed freeze.
