- Convergence loop now uses FillLinear internally to measure actual
waste with geometry-aware spacing instead of bounding-box arithmetic
- Each candidate pair is tried in both Row and Column orientations to
find the shortest perpendicular dimension (more complete stripes)
- CompleteStripesOnly flag drops partial stripes; remnant strip is
filled by a full engine run (injected via CreateRemnantEngine)
- ConvergeStripeAngleShrink tries N+1 narrower pairs as alternative
- FillResultCache avoids redundant engine runs on same-sized remnants
- CLAUDE.md: note to not commit specs/plans

The convergence loop now ensures the pair starts with its short side
parallel to the primary axis, maximizing the number of pairs that fit.
Also adds ConvergeStripeAngleShrink to try N+1 narrower pairs, and
evaluates both expand and shrink results to pick the better grid.
