A clamp rail can now carry its own Clearance, the gap parts keep from
every clamp footprint, independent of part spacing. Unset, it keeps the
sheet's bottom edge spacing as before. Clamp blocks drawn under the
sheet can use close to zero so the laser only stays off them.
Plate.ClampClearance and NestPlateStock.ClampClearance resolve it once;
the engines, interactive fill/pack/push, the layout check, Expander walls
and automatic cut-off placement all read it. The interactive push now
holds clamps at their square clearance keep-out (the layout check's
shape) instead of the part spacing, so parts no longer tuck into its
corners; the clamped fill characterization digests are re-pinned after
checking the new layouts validate.
Persisted as an optional `clearance` on the .nest clamp rail and the
machine clamp settings; edited in Nest > Clamps and the machine's
Clamps tab.

Rectangular stock serializes exactly as before, so result digests that
hash the whole result are unchanged.

NestPlateStock carries the outline; its usable material (less obstacles,
eroded by the largest edge spacing) becomes the FrontierPacker's
PackBoundary. The layout check and the runner's candidate validation
reject a part outside the outline or over an obstacle, area-based cost
and the area budget use the material area, salvage credits nothing, and
Rectangles, Circles, FlatBar and the fill strategies place nothing on it.

Last-resort removal ran on any clamped stock, but only a rail-following
plate can record which clamp to pull and its removal time: an explicit-zone
target lost the instruction entirely. NestPlateStock now carries the rail its
zones were resolved from (NestStockBuilder, DrawingJobMapper.FromPlate);
recovery removes clamps only from rail-backed stock, and commit falls back to
the stock's rail when the target plate has none. Runs are now ordered by
distance from the origin along the edge, not by zone list order.

NestPlateStock is documented as immutable input, but ClampZones handed
out its own zones, whose bounds are mutable. Editing one after the
stock was built moved the stock's clamp while plates materialized from
the stock (layout check, fill, posting) kept the original zone, so a
part or cut on the moved clamp validated and posted clear.
Return detached copies on every read, so the stock and its plates can
never disagree. Copies keep the exact bits; engine results are
unchanged.

Plates the engine built from stock (DrawingJobMapper.CreatePlate, used
by the public result materializer, the layout check and the placement
fillers) stored placement-frame zones, while live plates store them
relative to the sheet's lower-left corner. The same Plate.ClampZones
therefore meant two frames: the new clamp cut checks double-translated
materialized plates in quadrants 2-4, and interactive fill and push on
live plates read sheet-frame zones as placement coordinates, so they
could put parts on clamps there.
Plates built from stock now keep the stock's input zones (sheet frame,
no lossy translate-and-back), and the layout check and interactive
clamp obstacles map through ClampZoneFrame.ToPlacement, which
reproduces the stock's placement zones bit for bit, so engine
placements and validation are unchanged.

NestPlateStock takes an optional clamp-zone list, translated into the
placement frame exactly like WorkArea (quadrants 1-4) and detached from
caller boxes; empty input keeps stock bit-identical to before. Plate
mappings (DrawingJobMapper.FromPlate/CreatePlate, NestStockBuilder) map
zones across; materialized plates carry them for checking.
NestJobValidator rejects zones outside the sheet or duplicate ids.
RepeatedPlateGrouping and NestLayoutCheck treat clamp sets as stock
identity (C8), and the layout checker flags part material inside a zone
inflated by bottom-edge spacing with the shared spacing slack (C1/C5) -
no tolerance loosened.
Every plugin engine re-derived the quadrant/edge-spacing work area by hand
(Gpt6Astra, Opus55 and Qwen each had a copy, as did the placement
validator). One definition on the stock removes that duplication and the
chance of an engine disagreeing with the validator's bounds.

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.
