    GamePath Configuration
    ============================================================================

    PURPOSE:
    This file centralizes the Stardew Valley game installation path configuration
    to avoid hardcoding it in multiple places (Makefile, .csproj files, scripts).

    WHY IT EXISTS:
    - Previously, the game path was hardcoded in both Makefile and JunimoServer.csproj
    - This made it difficult to maintain and required changes in multiple files
    - Now, GAME_PATH is defined once in .env and automatically loaded by this file

    HOW IT WORKS:
    - MSBuild automatically imports Directory.Build.props from parent directories
    - This file reads the .env file and extracts the GAME_PATH value using regex
    - The GamePath property is set and becomes available to all .csproj files
    - The $(GamePath) variable is used in csproj for DLL references and mod building

    SCOPE:
    - Applies to ALL .NET projects in this repository (current and future)
    - Located at repo root so .env and Directory.Build.props are colocated

    USAGE:
    1. Set GAME_PATH in .env file (use forward slashes for cross-platform compatibility)
    2. Build normally: dotnet build or make build-mod
    3. GamePath is automatically available in all projects

    PRIORITY ORDER:
    1. Command line: /p:GamePath=... (highest priority, for one-off overrides)
    2. .env file: GAME_PATH=... (normal usage, single source of truth)
    3. Environment variable: GAME_PATH (fallback if .env doesn't exist)

    RELATED FILES:
    - .env (and .env.example): Defines GAME_PATH
    - mod/JunimoServer/JunimoServer.csproj: Uses $(GamePath) for DLL references
    - Makefile: Loads .env for other build variables
    - tools/decompile-sdv.sh: Uses GAME_PATH environment variable
