Replace Extensions.Grok project with xAI NuGet package

[Copilot]

The Extensions.Grok project is now redundant as the xAI NuGet package provides identical functionality.

Changes

• Deleted src/Extensions.Grok/ - Entire project (GrokClient, GrokChatClient, GrokChatOptions, etc.)
• Deleted src/Tests/GrokTests.cs - Associated test file
• Updated project references - Removed Extensions.Grok from solution, Tests.csproj, and Extensions.csproj
• Added xAI package dependency - <PackageReference Include="xAI" Version="1.0.2" /> in Extensions.csproj
• Updated namespace imports - Changed Devlooped.Extensions.AI.Grok → xAI in ConfigurableChatClient.cs and ConfigurableAIAgent.cs
• Updated readme.md - Replaced detailed Grok docs with reference to xAI package

Migration

// Before
using Devlooped.Extensions.AI.Grok;

// After  
using xAI;

The GrokClient, GrokChatOptions, and related types remain available with the same API via the xAI package.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• pkg.kzu.app
  • Triggering command: /usr/bin/dotnet dotnet restore (dns block)
  • Triggering command: /usr/bin/dotnet dotnet restore --ignore-failed-sources 53 -j ACCEPT (dns block)
  • Triggering command: /usr/bin/dotnet dotnet build --ignore-failed-sources (dns block)
• www.nuget.org
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Replace the Extensions.Grok project with the nuget package xAI which provides the same behavior now. Delete the entire project and any test files related to it.
