iterative fill workflow.

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.

Visual Studio re-serialized the designer — removes `this.` prefixes,
modernizes event handler syntax, trims trailing whitespace in resx.

StripNestEngine only overrode Fill(NestItem), so ActionClone.Fill
and Pack operations fell through to the empty base class defaults.
Now all virtual methods delegate to DefaultNestEngine.

Wrap IProgress with AccumulatingProgress so remnant fills prepend
previously placed strip parts to each report. The UI now shows the
full picture (red + purple) instead of replacing strip parts.

Nest() now deducts placed counts from input NestItem.Quantity so the
UI loop doesn't create extra plates. All inner DefaultNestEngine.Fill
calls forward the IProgress parameter for live progress updates.

The auto-nest code paths (MainForm, MCP, Console) now call
engine.Nest(items, progress, token) instead of manually orchestrating
sequential fill+pack. The default implementation in NestEngineBase
does sequential FillExact+PackArea. StripNestEngine overrides with
its strip strategy. This makes the engine dropdown actually work.
Also consolidates ComputeRemainderWithin into NestEngineBase,
removing duplicates from MainForm and StripNestEngine.

When Strip is selected in the engine dropdown, RunAutoNest_Click
calls StripNestEngine.Nest() instead of sequential FillExact+Pack.

Runs strip and sequential strategies in competition, picks the
denser result. Reports scores for both strategies in output.
