 - Ensured checkbox state and row highlight state stay fully in sync for all rows in a shift multi-selection.
 - Corrected selection logic so every row within the calculated range is consistently selected and marked.

+## v20260101-11-run-checks-select-all-indeterminate-clear-selection
+
+- Fixed the Run Checks header “select all” checkbox behavior: when the checkbox is in an indeterminate (partial selection) state, clicking it now clears all selected rows instead of selecting all rows.
+- Prevented unintended full selection when toggling from an indeterminate state.
+- Ensured consistent behavior between mouse click and keyboard (Space) interaction on the header checkbox.
