Private copies of tolerant box containment, box union, vector rotation and
the cutout proposals' coordinate-range check now use one helper each:
BoundingBox.IsWithin and BoundingBox.Union, Vector.Rotate, and
CutoutCoordinates.WithinRange. Tests pin the helpers bit-for-bit against
frozen copies of the removed bodies. No behavior change.

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.

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.

Desktop Auto Nest's "Best plan so far" strip now fills in for every built-in
whole-job engine except FlatBar, not only Irregular.
- Rectangles makes one sheet-by-sheet run, so it reports the finished job as
its one plan, then replays its plate commits (token checked as before).
- Circles reports when a stock-preference run or a tail re-plan beats its
best result so far.
- Default scores each candidate plan as it ranks results (valid, fewest
unplaced, lowest cost, candidate order) and reports it only when it beats
every plan already shown, so a later candidate never shows a worse plan.
The chosen result is always the last plan reported.
- Shared ReportPlan/SameLayout helpers on CandidateProgress; Irregular uses
them too. Reporting never changes the search.

- The cutout router uses the circle packer alone for a round hole whose
inserts are all round. Lattice and NFP never placed more there, and when
demand exceeded what fit they spent 20+ minutes on one job.
- The cutout pre-pass skips a hole whose area is smaller than an insert's
outline, so bolt holes no longer run the searches.
- Circles re-packs its last sheet, and its last two sheets together, onto
each single stock and keeps the result when the whole job gets cheaper.
On 14 real round-part jobs costs are unchanged and pipeline time drops from
262 s to 144 s for Circles and 355 s to 245 s for Default.

Circles packs every part as its minimum enclosing circle at centers tangent
to two of the work-area walls, placed discs and clamp keep-outs, bottom-left
and left-bottom, with hexagonal and square lattice seeds. It bids only when
every part fills at least 0.8 of its enclosing circle and otherwise returns
everything unplaced at once. Default runs it as a third candidate.
Rectangles' sheet-by-sheet stock loop moves to NestingEngines/SheetByStock
(Rectangles output unchanged) and Default's candidate scoring and commit
forwarding become shared helpers. Circles also runs the whole job preferring
each offered stock and keeps the best result. Contract tests take shapes an
engine can override.
Synthetic round jobs, salvage-credited: Circles wins or ties all six with
valid layouts; Default cost falls about 4% versus Irregular alone.
