Assign Lead-ins (LeadInAssigner) now leaves every unlocked part with active
drawing pins unchanged and returns those parts, so it never overwrites a pin
with the plate's settings; the desktop names them ("N parts kept their
drawing lead-ins (plate P: parts ...); use Plan Cutting to apply their
drawing pins."). Parts without pins, with pins switched off, or locked are
assigned or skipped exactly as before.
The pre-post review now covers drawing pins. A part with active pins whose
placed program does not cut each pinned contour exactly as the pin's own
emission (re-emitted with the part's cutting settings and matched motion for
motion) warns "Drawing pins not applied", as do locked lead-ins overriding
pins and a pin that no longer matches the geometry; pins switched off are
not reported. The contours that are cut as pinned join locked programs in
the fixed-lead re-check against every part's clean material, and fixed
leads are now also checked against active clamps (Plan Cutting itself does
not model clamps).
AGENTS.md records the fixed-emission safeguard and the characterization
digests.

Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
External lead-ins now sit on the line between the last internal cutout
and the next part's first pierce point, minimizing rapid travel. Cutout
sequencing starts from the bounding box corner opposite the origin and
iterates 3 times to converge the perimeter lead-in and internal sequence.
LeadInAssigner and PlateProcessor both use a two-pass approach: first
pass collects pierce points, second pass refines with next-part knowledge.
