Reverse S4 auto-select (empty=silence+empty state), add peak-thumbnail capture browser + bank filter + keyboard-strip drag machine, v3 component state (selection + zones), and the S-NAME-1 filename/display rename (UID locked). MSVC min/max macro collisions fixed post-implementation; 26/26 tests green.
