- FillExtents.Fill reported progress internally which overwrote the UI's
temporary parts even when a better result (e.g. Pairs with 70 parts)
won the competition. Added final ReportProgress call in FindBestFill
and Fill(groupParts) to ensure the UI always shows the actual winner.
- FillExtents vertical copy distance clamp (Math.Max with pairHeight +
spacing) prevented geometry-aware compaction from ever occurring,
causing visible gaps between rows. Boundaries are already inflated by
halfSpacing so the calculated distance is correct; only fall back to
bounding-box distance on non-positive results.
- PairFiller now sets RemainderPatterns on FillLinear so remainder strips
get pair-based filling instead of only individual parts (+1 part in
tight layouts).

Replace RepeatColumns stub with real implementation: compacts a test column
left against column 1 to derive the copy distance, tiles further columns at
that interval, and clips partial columns to the work area bounds. Adds 4 new
FillExtentsTests covering multi-column fill, rect shapes, non-zero-origin
work areas, and cancellation.

Replace AdjustColumn stub with a convergence loop that distributes the
remaining gap between the topmost part and the work area top edge across
all pairs. TryAdjustPair/TryShiftDirection try shifting part2 up (or down
as fallback) and compact left, rejecting moves that widen the pair.
