chore: remove tools directory

Browse Source 
One-off helper utilities don't belong in the repo. PepNestExport moved to
/home/aj/src/PepNestExport as a standalone companion project; NestDxfJob and
StreamGravographJob are removed (recoverable from history).

**Single-plate placement:** interactive fills use `PlateFillService`, which explicitly selects one of `Default`, `Strip`, `Vertical Remnant`, or `Horizontal Remnant` and returns proposed parts without mutating the caller's plate. The caller remains responsible for preview accept/cancel and attachment. Whole-job work in the desktop app, console, MCP server, and public API resolves a named `INestingEngine`, solves one `NestJob`, and materializes committed results. `NestRunner.RunAsync` reports status, stop reason, part fulfillment, stock usage, and plate-to-stock mapping; `.nestquote` archives carry a schema version and round-trip incomplete jobs.
### Fresh DXF job verification (headless)
`tools/NestDxfJob` imports a complete quantity workbook and runs a registered whole-job engine. It never reuses saved drawing geometry or placements. The workbook must have a `Parts` worksheet with exactly one `Part Name` and `Qty Required` column; names match DXF filename stems exactly. Invalid/fractional/negative quantities, duplicate names, and missing required DXFs fail explicitly. Zero-demand rows are not imported; additional DXFs with no positive workbook demand are listed and not assigned an invented quantity.
```bash
dotnet run --project tools/NestDxfJob -- \
/path/to/dxfs /path/to/parts.xlsx /path/to/settings.nest \
/path/to/new-results-directory Strip
```
The settings nest supplies units, material metadata, per-part rotation constraints/priority where names match, and distinct plate dimensions/clearances/quadrants. Stock is unlimited copies of those settings with a 40-sheet cap, not a claim about physical inventory. DXFs with explicit conflicting units reject; unitless DXFs use the template units without rescaling. `CadImporter` is called with `DetectBends = false`: default DXF filtering removes case-insensitive `ETCH`/`SCRIBE` layers before optimization, and bend detection cannot regenerate marks.
The output directory must not exist. The tool writes `imported-cut-only.nest` and `import-report.json` (including input hashes, excluded marks, and unmatched DXFs), then runs the selected engine with a ten-minute cancellation budget. A complete result must pass quantity, bounds, overlap/spacing and cut-only checks, then save/reload and pass them again before success. `validation-report.json` records per-part fulfillment and placements. A partial or invalid result exits nonzero and is not published as a successful nest. Use `import-only` instead of an engine name to verify and save only the imported job. This verifies nesting geometry, not machine-ready CNC lead-ins or post-processing.
### PEP nest export (benchmark against PEP)
`tools/PepNestExport` converts a year of PEP nests into `.nest` files for `OpenNest.Benchmark`. It lists nests from PepApi (`/nests/{year}`), downloads each `.pep` file (`/nests/{year}/{name}/download`), and reads it with `PepLib.Core` from the sibling `PepApi.Core` repo. Override the path with `-p:PepLibProject=<path>` if that repo is cloned elsewhere.
```bash
dotnet run --project tools/PepNestExport -c Release -- "/path/to/PEP 2026 nests" --year 2026
dotnet OpenNest.Benchmark/bin/Release/net8.0/OpenNest.Benchmark.dll "/path/to/PEP 2026 nests" --engines Opus55NestingEngine --csv results.csv
```
Each `.nest` keeps PEP's own layout: plate sizes and duplicate counts, part spacing, edge spacing, quadrant and every placement. The benchmark therefore scores PEP as its `Baseline` row and offers engines only the sheet sizes PEP used, unless you pass `--sheet-sizes`. Drawing geometry comes from PEP's loops, flattened with sub-loop (hole) calls continuing the incremental position. Lead-ins, lead-outs, scribe, display and `DESTRUCT CUT` moves are dropped, and uncut micro-joint tabs of 0.25 or less are closed: open cut runs are chained end to start across the tab and bridged with a cut line, but only where they form a closed loop, so separate contours that happen to lie close together are never merged. The tabs themselves are not kept. Skeleton and display-only parts are excluded.
By default `--quantity nested` sets demand to what PEP actually nested; `--quantity required` uses PEP's required counts instead. Other options: `--nests`, `--status` (default: every status except `Deleted`), `--parallel` and `--force`.
The tool writes `pep-baseline.csv` (sheets, sheet area, part area and utilization per nest) and a `<nest>.violations.txt` when PEP's layout fails validation. PEP places parts at exactly the nominal spacing and rounds coordinates to about 4 decimals, so the strict benchmark validator usually rejects the PEP baseline. Its sheet count and area still show in the report. `RelaxedValid` repeats the check allowing 0.025 on spacing and 0.001 on edges; a failure there means a real overlap or a genuinely tight manual placement. Validation runs on the saved file and is capped at 60 seconds per nest: `NestValidator` can take minutes on parts with hundreds of outline segments and many holes, and those rows report `timeout`. Programs are stored incremental, like CAD-imported drawings, because the desktop renderer only applies part locations to incremental programs.
