Move fill algorithms to OpenNest.Engine.Fill namespace:
FillLinear, FillExtents, PairFiller, ShrinkFiller, Compactor,
RemnantFiller, RemnantFinder, FillScore, Pattern, PatternTiler,
PartBoundary, RotationAnalysis, AngleCandidateBuilder, and
AccumulatingProgress.
Move strategy layer to OpenNest.Engine.Strategies namespace:
IFillStrategy, FillContext, FillStrategyRegistry, FillHelpers,
and all built-in strategy implementations.
Add using directives to all consuming files across Engine, UI,
MCP, and Tests projects.

Add FileExtension and FileFilter constants to NestFormat and update all
references across Console, MCP, Training, and WinForms projects.

The auto-nest code paths (MainForm, MCP, Console) now call
engine.Nest(items, progress, token) instead of manually orchestrating
sequential fill+pack. The default implementation in NestEngineBase
does sequential FillExact+PackArea. StripNestEngine overrides with
its strip strategy. This makes the engine dropdown actually work.
Also consolidates ComputeRemainderWithin into NestEngineBase,
removing duplicates from MainForm and StripNestEngine.

Runs strip and sequential strategies in competition, picks the
denser result. Reports scores for both strategies in output.

ComputeRemainderStrip used the bounding box of ALL plate parts against
the full plate, missing large interior gaps between drawing groups.
Now computes remainder within the current work area based on only the
parts that were just placed. This lets subsequent drawings fill the
gap between previous drawing groups instead of being forced into a
tiny strip at the plate edge.

Move NFP-based AutoNest logic (polygon extraction, rotation computation,
simulated annealing) into dedicated AutoNester class. Consolidate duplicate
FillWithPairs overloads, extract BuildCandidateAngles and BuildProgressSummary,
reorganize NestEngine into logical sections. Update callers in Console,
MCP tools, and MainForm to use AutoNester.Nest.

Brings in the full NFP implementation: ConvexDecomposition, NoFitPolygon,
InnerFitPolygon, NfpCache, BottomLeftFill, SimulatedAnnealing optimizer,
and INestOptimizer interface. Resolves conflicts by keeping master's
progress reporting infrastructure alongside the new AutoNest methods,
and adapting RunAutoNest_Click to use NFP AutoNest with async/cancellation.

"Length" is more natural than "height" for flat plate materials.
Renames the field on OpenNest.Geometry.Size, Box.Height property,
and all references across 38 files.

Implement geometry-aware nesting using No-Fit Polygons and simulated
annealing optimization. Parts interlock based on true shape rather than
bounding boxes, producing tighter layouts for mixed-part scenarios.
New types in Core/Geometry:
- ConvexDecomposition: ear-clipping triangulation for concave polygons
- NoFitPolygon: Minkowski sum via convex decomposition + Clipper2 union
- InnerFitPolygon: feasible region computation for plate placement
New types in Engine:
- NfpCache: caches NFPs keyed by (drawingId, rotation) pairs
- BottomLeftFill: places parts using feasible regions from IFP - NFP union
- INestOptimizer: abstraction for future GA/parallel upgrades
- SimulatedAnnealing: optimizes part ordering and rotation
Integration:
- NestEngine.AutoNest(): new public entry point for mixed-part nesting
- MainForm.RunAutoNest_Click: uses AutoNest instead of Pack
- NestingTools.autonest_plate: new MCP tool for Claude Code integration
- Drawing.Id: auto-incrementing identifier for NFP cache keys
- Clipper2 NuGet added to OpenNest.Core for polygon boolean operations

Console app for running the nesting engine from the command line.
Supports plate size/spacing overrides, quantity limits, overlap
checking with exit codes, and benchmark-friendly flags (--no-save,
--no-log). The MCP test_engine tool shells out to this project.
