feat: Factorio Space Age Production Calculator

- Domain: immutable entities (Resource, Recipe, Machine, Module, etc.) - Data: JSON recipe repository (34 resources, 26 recipes, Space Age) - Solver: DFS-based production planner with module support - Reporting: Console, JSON, Excel exporters - CLI: solve/list commands with Spectre.Console - Tests: 20 unit tests (xUnit) all passing - Tech: C# .NET 10, MathNet.Numerics, ClosedXML Model: GPT-4.1 (OpenAI) — executed by pi coding agent
