S10: capture-first ReaSampler 9000 editor — browser, single-capture setup, zones toggle

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.
