This pull request implements the core logic for the copper pour solver. It introduces a complete
pipeline that takes a circuit-json input and generates B-Rep shapes for the copper pour regions.
Key changes include:
• Copper Pour Solver Implementation: The CopperPourPipelineSolver is built out to process
obstacles, perform boolean geometry operations using flatten-js, and generate final B-Rep
shapes.
• Circuit JSON Conversion: A new function convertCircuitJsonToInputProblem is added to
translate standard circuit-json elements (pads, traces, holes) into the solver's internal
InputProblem format.
• Comprehensive Testing: A suite of snapshot tests has been added, rendering the output of the
solver to SVG for multiple circuit configurations to visually validate the results.
• Type Definitions: Updated lib/types.ts to support various pad shapes (rect, circle, trace)
and define the solver's input and output structures.
• Dependency Updates: Added @flatten-js/core for geometric calculations and circuit-to-svg for
test rendering.
