- Introduce Config class for managing computation backend selection - Add abstract PolygonBackend base class defining geom that delegates operations to RPC server - Add backend_factoryetry operation interface - Implement ServerBackend for dynamic backend selection based on configuration - Refactor PolygonData to use backend abstraction instead of direct server calls - Support configuration via PYEDB_COMPUTATION_BACKEND environment variable - Backend selection: 'server' (gRPC), 'shapely' (local), 'auto' (default: server)

- Implement ShapelyBackend class with local polygon operations using Shapely library - Add arc tessellation with configurable chord error, angle, and point limits - Support for all polygon operations: area, convex hull, intersections, transformations - Implement geometry predicates: is_convex, is_circle, is_box, is_inside - Add polygon set operations: unite, intersect, subtract, xor - Support polygon modifications: move, rotate, scale, mirror, expand, defeature - Add helper methods for closest points, bounding boxes, and circle intersections - Include comprehensive test suite covering all backend operations - Add test fixtures and utilities for polygon creation with arcs and holes - Support both server and Shapely backends with configurable selection
