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.

FlangeShape generates an outer circle with evenly-spaced bolt holes
on a bolt circle pattern. ShapeDefinition.LoadFromJson<T>() provides
generic JSON loading for any shape — no separate preset classes needed.

Two bugs caused the remnant finder to miss valid empty regions:
1. RemoveDominated used an 80% overlap-area threshold that incorrectly
removed L-shaped remnants. A tall strip to one side would "dominate"
wide strips above/below it even though they represent different usable
space. Replaced with geometric containment check — only remove a box
if it's fully inside a larger one.
2. FindTieredRemnants split remnants at the obstacle envelope boundary,
and both pieces could fall below minDimension even though the original
remnant passed the filter (e.g., 6.6" remnant split into 5.35" + 1.25"
with minDim=5.38"). Added fallback to keep the original unsplit.

Renamed OpenNest.Engine.Tests → OpenNest.Tests (directory, .csproj,
namespaces in all .cs files). Added OpenNest.IO project reference.
