Consolidated two stateless classes into one unified API: Dxf.Import(),
Dxf.GetGeometry(), Dxf.ExportPlate(), Dxf.ExportProgram(). Export
state moved into a private ExportContext. Removed bool+out pattern
from GetGeometry in favor of returning empty list on failure.

Always keep a trailing empty plate so users can immediately place parts
without manually adding a plate. Auto-appends a new sentinel when parts
land on the last plate; trims excess trailing empties on removal.
Plate list now shows Parts count and Utilization % columns. Empty plates
are filtered from save and export. Sentinel updates are deferred via
BeginInvoke to avoid collection-modified exceptions and debounced to
prevent per-part overhead on bulk operations.

Stateless orchestrator that takes a NestRequest and returns a NestResponse.
Imports DXFs, builds NestItems, runs the engine in a multi-plate loop until
all parts are placed, computes timing, and returns utilization metrics.

Adds NestResponse type to OpenNest.Api with SaveAsync/LoadAsync for .nestquote format — a ZIP containing request.json, response.json (metrics), and an embedded nest.nest.

Relocates CutParameters from OpenNest namespace to OpenNest.Api, adds
LeadInLength and PostProcessor properties, and provides a typed Default
factory. Updates Timing.cs, the WinForms project reference, and the three
consuming forms to resolve the type from the new namespace.
