Initial commit: terminal Minesweeper in C# for .NET 10

A playable console Minesweeper (arrow keys, chording, flags, question marks, pause, difficulty presets) plus a deduction-and-guess solver that can play the game headlessly. Game logic lives in src/Minesweeper/Game and has no console dependencies, so it is covered by 65 unit tests. Includes publishing helpers for self-contained, trimmed single-file binaries (publish.sh) and an .editorconfig that the sources conform to: UTF-8 BOM and 4-space indents for C#, 2-space indents for project files, LF endings and 2-space indents for shell scripts, System-first usings, no redundant `this.`, and s_/ _ prefixed private static and instance fields.
