After the main single-pass placement, leftover items are now packed
together using the engine's multi-item Nest()/PackArea() methods
instead of creating one plate per drawing. First tries packing into
remaining space on existing plates, then creates shared plates for
anything still remaining.

Previously, parts classified as "Large" skipped all existing plates
and always created new ones. This caused one-unique-part-per-plate
behavior since most parts exceed half the plate dimension. Now large
parts search viable remnants on existing plates before creating new
ones, matching the intended part-first behavior.

Small parts must only go into scrap zones (both dims < minRemnantSize)
to preserve viable remnants. The implementer had inverted this, giving
small parts access to all remnants. Also fixed the test to verify
remnant preservation behavior and removed unused FindAllRemnants helper.

Implements the main Nest() method that ties together sorting,
classification, and placement across multiple plates. The method
processes items largest-first, placing medium/small parts into
remnant zones on existing plates before creating new ones. Includes
private helpers: TryPlaceOnExistingPlates, PlaceOnNewPlates,
TryUpgradeOrNewPlate, FindAllRemnants, and CloneItem.

Adds IsScrapRemnant(), FindScrapZones(), and FindViableRemnants() to
MultiPlateNester. A remnant is scrap only when both dimensions fall
below the minimum remnant size threshold (AND logic, not OR).

Introduces PartClass enum and Classify() static method that categorizes
parts as Large (exceeds half work area in either dimension), Medium
(area > 1/9 work area), or Small.
