feat: wire IFillComparer through FillHelpers, Linear, and Extents strategies

Browse Source 
- FillHelpers.FillPattern gains optional IFillComparer parameter; falls back to FillScore when null
- LinearFillStrategy.Fill replaced with FillWithDirectionPreference + comparer from context.Policy
- ExtentsFillStrategy.Fill replaced with comparer.IsBetter, removing FillScore comparison
- DefaultNestEngine group-fill path resolves Task 6 TODO, passing Comparer to FillPattern
