feat(tools): PepNestExport converts PEP nests into benchmark .nest files

Browse Source 
Converts a PepApi year of PEP nests into .nest files that keep PEP's own
placements, so OpenNest.Benchmark can score PEP as its Baseline row.

Micro-joint tabs: PEP leaves tabs uncut by jumping them with a rapid, at a
contour's seam or partway along it (a cutout cut as two halves 0.02 apart).
The part still occupies that material, so open cut runs are chained end to
start across gaps up to 0.25 and bridged with a cut line, but only where
they close into a loop, so separate contours that lie close together (two
circles 0.25 apart) are never merged. Previously only seam tabs were closed,
leaving mid-contour tabbed cutouts open and the validator reading them as
garbage regions.

- `NestValidator` checks the returned layout: every part inside `Plate.WorkArea()`, every pair at least `Plate.PartSpacing` apart (checked geometrically: each part's perimeter inflated and cutouts shrunk by the spacing, tested against the other part's raw material with holes subtracted, so part-in-part inside a cutout is legal; an X-sorted bounding-box sweep prunes distant pairs), and no drawing over its requested quantity. `ValidateAgainstJob` also checks the raw `NestJobResult`: every sheet must match a stock entry the job offered (size, spacing, edge spacing, quadrant; finite quantity not overdrawn), and every placement rotation must satisfy its part's `RotationPolicy.Allows`. An invalid, throwing, or timed-out run places nothing for scoring.
- Ranking (`Report.Compare`): valid > invalid, fully placed > not, then lower `JobResult.Cost`, then fewer plates. Cost = salvage-credited sheet area (`StockLadderNestingEngine.EstimateNetArea` per plate, recomputed from job geometry) + `BenchmarkJob.UnplacedPartPenalty` (largest candidate sheet area) per unplaced part, so dropping hard parts never improves the score. The summary sums cost and areas across jobs (area-weighted, not a mean of per-job percentages). Without `--sheet-sizes`, `.nest` jobs only offer their original sizes, and the CLI warns that this hints engines. Numeric CLI and manifest sheet sizes parse with the invariant culture (`JobLoader.TryParseSheetSize`).
- `--engines Name1,Name2` filters to specific registered engines (default: all); `--csv <path>` writes a flat per-job CSV alongside the console report.
- `tools/PepNestExport` (outside the solution; references `PepLib.Core` from the sibling `PepApi.Core` repo) converts a PepApi year of PEP nests into `.nest` files that keep PEP's placements as the benchmark `Baseline`. PEP loop quirks: sub-loop calls continue the incremental position; lead-in/out, `DESTRUCT CUT` and non-cut moves must not reach the program as rapids (a program's bounding box counts rapid endpoints); contours may be broken by uncut micro-joint tabs (a rapid of up to 0.25 across the tab, at the seam or mid-contour, e.g. a cutout cut as two halves), which the export bridges only where the pieces chain into a closed loop; and one drawing can be placed through several loops with different origins.
