Added dynamic version resolution from the `<Version>` tag in the
`.csproj` file, enabling versioned output directories. Updated
`setlocal` to use `enabledelayedexpansion` for better variable
handling. Enhanced logging of build parameters and streamlined
the "Publishing" step by removing redundant logs.
Improved output verification with additional checks for critical
files (`hostfxr.dll`, `coreclr.dll`, etc.), logging failures if
files are missing. Updated success messages to include the
resolved version and generalized next-step instructions.
Added a `dotnet-tools.json` file to define a .NET tool manifest, specifying the `dotnet-ef` tool with version `10.0.9`.
Introduced a `publish.bat` script for publishing the `EnvelopeGenerator.Server` project as a self-contained application targeting `win-x64` and .NET 8. The script handles cleaning, publishing, output verification, and provides deployment instructions for IIS.
Updated the `EnvelopeGenerator.sln` file to include a reference to the `publish.bat` script under the `EnvelopeGenerator.Server` project using a `SolutionItems` section.
