Add JsonDumper tool for SchDoc to JSON export

[profff]

Summary

JsonDumper is a command-line tool that reads Altium SchDoc schematic files and exports their contents to JSON format. This enables integration with external analysis tools and automation pipelines.

Features

• Exports components with designators, library references, and parameters
• Exports pins with connection coordinates (ConnX/ConnY) for accurate netlist building
• Exports wires, netlabels, power ports, and other schematic primitives
• Supports batch processing of multiple SchDoc files

Usage

dotnet run --project JsonDumper/JsonDumper.csproj -- file1.SchDoc file2.SchDoc

Output Format

JSON structure with:

• FileName: Source file name
• Components: Array of components with pins
• Wires: Wire segments with vertex coordinates
• NetLabels: Net label text and positions
• PowerPorts: Power port symbols
• Other schematic primitives

Use Cases

• Automated netlist extraction
• Schematic analysis tools
• Integration with Python/other languages via JSON
• CI/CD pipelines for design validation
