daniel 34df2563e4 feat(m11): native OS drag-out of bank samples (copy-only)
Pure drag_out (gesture boundary + path-list assembly) + Windows OLE
CF_HDROP / SWELL file-list shell; bank_panel hands off when a dragged
selection leaves the client area. COPY-ONLY mask; internal drag intact.

// Standalone tests for reasampler::drag_out — no REAPER, no test framework. Same fast loop
// as the sibling pure tests (action_buttons / mode_switch et al.): assert the gesture-
// boundary decision and the path-list assembly directly.
//
// Covers (M11 drag-out brief §test cases):
// * Gesture boundary: inside-panel drag stays Internal; leaving the client area with
// armed samples -> OsDrag; no armed samples (or not dragging) -> None; half-open edge
// behavior; re-entry back inside returns to Internal (position-only decision).
// * Path-list assembly: single, multi, dedupe (cross-bank copy case), skip-missing,
// skip-unresolved, empty selection, order preservation, mixed tallies.
