Circles packs every part as its minimum enclosing circle at centers tangent
to two of the work-area walls, placed discs and clamp keep-outs, bottom-left
and left-bottom, with hexagonal and square lattice seeds. It bids only when
every part fills at least 0.8 of its enclosing circle and otherwise returns
everything unplaced at once. Default runs it as a third candidate.
Rectangles' sheet-by-sheet stock loop moves to NestingEngines/SheetByStock
(Rectangles output unchanged) and Default's candidate scoring and commit
forwarding become shared helpers. Circles also runs the whole job preferring
each offered stock and keeps the best result. Contract tests take shapes an
engine can override.
Synthetic round jobs, salvage-credited: Circles wins or ties all six with
valid layouts; Default cost falls about 4% versus Irregular alone.

Moves the two production plug-in engines into OpenNest.Engine under names
that describe the jobs they suit:
- Rectangles: plain and near-rectangular plates, maximal-rectangles box
packing (was the RectanglesNestingEngine plug-in)
- Irregular: irregular profiles, no-fit-polygon frontier packing (was the
Opus55NestingEngine plug-in)
Their tests and the shared engine contract/layout test kit move into
OpenNest.Engine.Tests/NestingEngines.
The registry maps the old plug-in names to the new engines, so saved desktop
selections, scripts and API requests keep working, and a leftover plug-in DLL
under an old name cannot shadow its replacement. Desktop startup passes the
registry's lookup when restoring the saved Auto Nest engine.
