Skip remnants that are too small to fit any remaining part, avoiding
wasted fill attempts. Recalculated each iteration as quantities deplete.

Remainder items were being filled into the full remnant box without
compaction. Added ShrinkFill helper that fills then shrinks the box
horizontally and vertically while maintaining the same part count.
This matches the strip item's shrink behavior and produces tighter
layouts that leave more usable space for subsequent items.

The iterative remnant fill was mutating shared NestItem.Quantity objects,
causing the second TryOrientation call (left) to see depleted quantities
from the first call (bottom). Use a local dictionary instead so both
orientations start with the full quantities.

Replace the single-pass guillotine split approach with RemnantFinder-based
iteration. After each fill, re-discover all free rectangles and try all
remaining items again until no more progress is made. This fills gaps that
were previously left empty after the initial strip + remainder layout.
Also change ActiveWorkArea border color from orange to red.

Extracts remnant detection from the nesting engine into a standalone
RemnantFinder class using edge projection algorithm, enabling an
iterative nest-area -> get-remnants workflow.

ComputeRemainderWithin only returned the larger of two possible free
rectangles, permanently losing usable area on the other axis after each
remainder item was placed. Replace the single shrinking box with a list
of free rectangles using guillotine cuts so both sub-areas remain
available for subsequent items.

The sequencer returns parts ordered from exit point inward. Reverse
so part 1 is nearest the origin and cutting works outward.

Advanced sequencer with default 0.25 MinDistanceBetweenRowsColumns
puts every part in its own row, degenerating to a Y-sort. Switch to
LeastCode (nearest-neighbor + 2-opt) for visible results.
Also replace AddRange(linq) with foreach+Add to avoid ObservableList
AddRange re-enumerating a deferred LINQ query for event firing.

Replace old SequenceByNearest with PartSequencerFactory using default
SequenceParameters (Advanced method with serpentine row grouping).

Renamed OpenNest.Engine.Tests → OpenNest.Tests (directory, .csproj,
namespaces in all .cs files). Added OpenNest.IO project reference.

16 tasks covering test infrastructure, core model changes, part sequencing
(6 strategies + factory), rapid planning (2 strategies), and the PlateProcessor
orchestrator. TDD approach with xUnit tests for each component.

Fix coordinate transforms (translate-only, no rotation), make orchestrator
non-destructive (ProcessedPart holds result instead of mutating Part.Program),
use readonly structs consistently, add factory mapping and known limitations.
