Tidy upper graph clutter

 - Live, non-blocking agent run indicators in the desktop UI (phase updates + progress bars while fix suggestions are generated, then auto-hidden when the run ends)
 - Three-column desktop workspace layout: errors (left), graph (center, primary), and a suggestion panel (right) that appears only after an agent workflow run starts
 - Graph force-layout simulation is intentionally reheated only on initial analyze and `Reset view`; selecting nodes or left-panel errors preserves the current arrangement
+- Graph readability tuning in default view: stronger node separation and stricter smart-label thresholds to reduce cluster clutter
 - `Reset view` also zooms to fit the currently visible graph so all rendered nodes are brought back into frame
 - Error list cards emphasize severity, message, and entity label; internal rule codes are hidden from the left-panel card headers
 - Suggestion lifecycle management across agent runs with a single active suggestion panel: close hides the panel, and per-error `Open Suggestion` actions re-open the latest generated suggestion without re-running the agent
