Expand test coverage from ~19% to ~25% of GAL API with modular scenario files:
- bezier-curves: Tests DrawCurve() with S-curves, waves, hearts, and control points
- arc-segments: Tests DrawArcSegment() with thick arc strokes (PCB trace style)
- segment-chain: Tests DrawSegmentChain() with zigzags, spirals, sharp corners
- group-caching: Tests BeginGroup/EndGroup/DrawGroup for cached geometry
Architecture:
- New scenarios in separate files under scenarios/
- Forward declarations in main gal_test_scenarios.cpp
- CMakeLists.txt updated to compile new scenario modules
Also:
- Remove unused build-wxwidgets-native.sh (using system wxWidgets)
