+fix: optimize log viewer TUI performance and improve run status colors
+
+- Remove continueToNextStep and resolveToolResults from tree event loading (~400MB → ~15MB)
+- Parallelize run event loading with Promise.all
+- Add header-based checkpoint filtering for run-specific queries (25x faster)
+- Use getFirstEvent for job query extraction instead of loading all events
+- Fix double statSync in checkpoint sort
+- Normalize run status colors: primary for completed/suspending, red for errors, muted for incomplete
