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.

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.

New NestEngineBase subclass that dedicates a tight strip to the
largest-area drawing and fills the remnant with remaining drawings.
Tries both bottom and left orientations, uses a shrink loop to find
the tightest strip, and picks the denser result.
