Detailed Description

Reactive QML type that observes a ChordRegion and exposes a QAbstractItemModel of ChordSegment rows.

Each row represents one chord as it should be drawn within the region's timeline bounds, taking loop iterations into account.

On any relevant input change (chord added/removed/moved, loop config changed, region resized), recalculate() rebuilds the segment list, a new QRangeModel is constructed (moving the data in), and segmentsChanged() is emitted.

Loop-expansion algorithm is ported from midi_region_canvas_renderer.cpp and shares the same semantics as MIDI region rendering.
