Brings the guided diagnostic (0.11.0 core/CLI) into the GUI:
- Each game row gets a "Run Diagnostic" button → starts a focused, game-tagged
capture and shows a recording banner (live sample count + GPU-lost indicator)
with Finish & analyze / Discard.
- Finishing runs core.diagnostic.finish() off the UI thread and opens a results
dialog (gui/diagnostic_dialog.py): window-scoped capture summary + findings
cards (reusing render_summary + finding_card).
- Banner restores on showEvent if a capture is still running (navigate away/back).
