- Evaluate pair candidates in parallel batches instead of sequentially
- Add GridDedup to skip duplicate pattern/direction/workArea combos
across PairFiller and StripeFiller strategies
- Replace crude 30% remnant area estimate with L-shaped geometry
calculation using actual grid extents and max utilization
- Move FillStrategyRegistry.SetEnabled to outer evaluation loop
to avoid repeated enable/disable per remnant fill

Replace stored property setters (BestPartCount, BestDensity, NestedWidth,
NestedLength, NestedArea) with computed properties that derive values from
BestParts, with a lazy cache invalidated on setter. Add internal
ProgressReport struct to replace the 7-parameter ReportProgress signature.
Update all 13 callsites and AccumulatingProgress. Delete FormatPhaseName
in favor of NestPhase.ShortName() extension.

Extract ConvergeFromAngle to deduplicate ~40 lines shared between
ConvergeStripeAngle and ConvergeStripeAngleShrink. Reduce BuildGrid
from 7 to 4 params and FillRemnant from 6 to 2 by reading context
fields directly. Remove unused angle parameter from FillRemnant.

PairFiller now accepts an optional IFillComparer (defaulting to
DefaultFillComparer) and uses it in EvaluateCandidates and
EvaluateCandidate/FillPattern instead of raw FillScore comparisons.
PairsFillStrategy passes context.Policy?.Comparer through.
StripeFiller derives _comparer from FillContext.Policy in its
constructor and uses it in Fill() instead of FillScore comparisons.

- 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.
