<#
.SYNOPSIS
Pushes NuGet packages (.nupkg) to a NuGet feed using nuget.exe.

.DESCRIPTION
- Reads API key from a local file (api.txt)
- Pushes all .nupkg in the artifacts folder
- Skips symbol packages by default (.snupkg)
- Can skip duplicates (recommended for CI)

.PREREQUISITES
- nuget.exe is present next to this script (or specify -NuGetExe)
- api.txt is present next to this script (or specify -ApiKeyFile)
- Packages exist in the artifacts folder (default: .\artifacts\nuget)
