Add OpenNest.IO/Bending/BendRepair: opt-in repair of unambiguous paired
ETCH/SCRIBE bend ticks, bounded to <=3.175 mm endpoint movement with
explicit source units. Cut geometry is never modified.
- CadImportOptions.BendRepair configures it; CadImportResult exposes
per-bend BendRepairReports; CadImporter/Dxf wire it into import.
- Console: --repair-bends-mm <limit> --cad-units inches|mm prints
per-bend reports for newly imported DXFs.
- New OpenNest.IO.Tests project (net8.0, synthetic DXFs, 30 tests)
covering bend detection and repair, added to the solution.
- Update README.md and CLAUDE.md for the new pipeline and build/test
instructions.
Loads any .nest file (or folder of them) via NestReader and nests every
drawing with quantity > 0 using each registered NestEngineBase, so it
works sight-unseen against arbitrary real jobs without any hardcoded
geometry. Optionally sweeps a fixed --sheet-sizes list instead of each
file's own plate size.
- BenchmarkJob/JobLoader build immutable job specs; a fresh Plate and
NestItem list is created per (job, engine) run so state never leaks
between engines or jobs.
- NestValidator rejects a layout if any part falls outside the work
area, any two parts are closer than PartSpacing (checked via each
part's own world-space polygon inflated by the spacing, so it holds
for arbitrary concave/holed geometry, not just bounding boxes), or a
drawing gets more parts than requested.
- Scoring matches Plate.Utilization() (placed area / full sheet area);
ties among fully-placed layouts break on the smaller used bounding
box (more usable remnant).
- Report prints a per-job ranked breakdown plus a per-engine summary
(wins, avg utilization, time), and can write a flat CSV.
Verified end-to-end against a synthetic .nest file (not committed)
against the four built-in engines; caught a genuine out-of-work-area
bug in StripNestEngine in the process.
Adds project dependency in .sln and project reference in OpenNest.csproj
so the Cincinnati post processor DLL builds before the main app, ensuring
it's always available in the Posts/ directory.

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

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.

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.

Test code and fixture data now live together in the OpenNest.Test repo
at git.thecozycat.net/aj/OpenNest.Test.git.

Move DxfImporter, DxfExporter, NestReader, NestWriter, ProgramReader,
and Extensions into a new OpenNest.IO class library. The WinForms project
now references OpenNest.IO instead of ACadSharp directly.

Introduces the OpenNest.Gpu class library with ILGPU dependencies and a
PartBitmap class that rasterizes Drawing closed shapes into integer grids
for GPU-based overlap testing. Supports rotation and spacing dilation.

Move all projects from Source/ to repository root for simpler navigation.
- Remove External/ dependency DLLs (will use NuGet packages)
- Remove Installer/ NSIS script
- Replace PartCollection/PlateCollection with ObservableList
- Add packages.config for NuGet dependencies
