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

Size.Parse and ToString now use WxL format (width first) matching the
natural convention. Fixed the Plate(w,l) constructor which was swapping
args when creating Size. Fixed PlateView.DrawPlate and DrawControl
ZoomToArea which had width/length mapped to the wrong screen axes.
Simplified Console --size parsing to use Size.TryParse instead of manual
split with confusing PlateHeight/PlateWidth fields. Added Command-Line
Interface section to README documenting all console options.

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.

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.

The BestFitFilter's aspect ratio cap of 5.0 was rejecting valid pair
candidates needed for narrow plates (e.g. 60x6.5, aspect 9.2) and
remainder strips on normal plates. Three fixes:
- BestFitFinder: derive MaxAspectRatio from the plate's own aspect
ratio so narrow plates don't reject all elongated pairs
- SelectPairCandidates: search the full unfiltered candidate list
(not just Keep=true) in strip mode, so pairs rejected by aspect
ratio for the main plate can still be used for narrow remainder
strips
- BestFitCache.Populate: skip caching empty result lists so stale
pre-computed data from nest files doesn't prevent recomputation
Also fixes console --size parsing to use LxW format matching
Size.Parse convention, and includes prior engine refactoring
(sequential fill loops, parallel FillPattern, pre-sorted edge
arrays in RotationSlideStrategy).

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.

Refactor flat top-level statements into NestConsole class with Options
and focused methods. Add support for passing .dxf files directly as
input — auto-imports geometry via DxfImporter and creates a fresh nest
with a plate when --size is specified. Supports three modes: nest-only,
DXF-only (requires --size), and mixed nest+DXF.

Move brute-force data collection, TrainingDatabase, and GPU init from
OpenNest.Console into a dedicated OpenNest.Training project. Replaces
raw Microsoft.Data.Sqlite with EF Core. Console is now a pure nesting
CLI with template support and cleaned-up usage output.

- Add verbose per-file and per-sheet-size console output during collection
- Skip already-processed parts at the sheet-size level instead of all-or-nothing
- Precompute best-fits once per part and reuse across all sheet sizes
- Clear best-fit cache after each part to prevent memory growth
- Save best-fits in separate bestfits/ zip entries instead of embedding in nest.json
- Filter to Keep=true results only and scope to plate sizes in the nest
- Set nest name to match filename (includes sheet size and part count)
- Add TrainingDatabase with per-run skip logic and SQLite schema

Wire up GpuEvaluatorFactory in the Console app the same way the GUI app
does, so BestFitCache uses GPU-accelerated slide computation when a
CUDA/OpenCL device is detected.

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.

- Change while(true) to bounded for-loop (max 100 plates) in MainForm
- Use Drawing.Name comparison instead of reference equality for quantity deduction
- Add Math.Max(0, ...) guard to prevent negative quantities
- Tune SA parameters for faster convergence (cooling=0.995, minTemp=0.1, maxNoImprove=500)
- Add --autonest flag to OpenNest.Console for CLI-based NFP autonesting

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.
