test: add contains(Point) hit-testing tests for all shapes

Add 36 tests covering bounds-based hit-testing (getBounds().contains(Point))
for SRectangle, SCircle, STriangle, SText, and SCollection:
- Point inside, outside, on boundary (inclusive top-left, exclusive bottom-right)
- Point after translate to verify position update
- SCollection union bounds, gap between children, single-child bounds

Closes #11
