@copilot The Blazor gateway is an optimized host for Blazor applications in general, not just for werbassembly. fix the description. No need to put the packs xxx as a tool

Fixed in 6c1c8b1: description now reads "Command line tool (blazor-gateway) for hosting Blazor applications." (also updated the Gateway package's own description and dropped the webassembly package tag) and removed the "packs as a .NET tool" wording.

Pull request overview
Adds a new Blazor Gateway dotnet-tool package (CLI) and introduces packaging + end-to-end installation tests to validate the produced tool can be installed and run. It also updates the Blazor WASM template test infrastructure to serve published standalone output using blazor-gateway instead of dotnet serve.
Changes:
- Adds
Microsoft.AspNetCore.Components.Gateway.Clipackaging project (nuspec + tool settings) that repackages the Gateway publish output as a dotnet tool. - Adds Gateway CLI package/installation tests plus supporting test infrastructure to locate locally-built packages and run the installed tool.
- Updates template test hosting to launch
blazor-gatewayagainst published output and derive the listening URL.
