chore(deps): consolidate PRs #525-#528 and enable optimistic Dependabot grouping

[jongalloway]

Summary

Consolidates current open Dependabot NuGet updates into one PR and configures Dependabot to aggressively minimize future NuGet PR count by grouping all NuGet dependencies together.

Supersedes: #525, #526, #527, #528.

Consolidated dependency updates

• Part 2 - Project Creation/GenAiLab/GenAiLab.Web/GenAiLab.Web.csproj

  • Microsoft.SemanticKernel.Core 1.77.0 -> 1.78.0 (Bump Microsoft.SemanticKernel.Core from 1.77.0 to 1.78.0 #525)

• Part 2 - Project Creation/GenAiLab/GenAiLab.ServiceDefaults/GenAiLab.ServiceDefaults.csproj

  • OpenTelemetry.Instrumentation.Runtime 1.15.1 -> 1.16.0 (Bump OpenTelemetry.Instrumentation.Runtime from 1.15.1 to 1.16.0 #526)

• Part 7 - MCP Server Basics/MyMcpServer/MyMcpServer.csproj

  • Microsoft.Extensions.Hosting 10.0.0-preview.6.25358.103 -> 10.0.9 (Bump Microsoft.Extensions.Hosting from 10.0.0-preview.6.25358.103 to 10.0.9 #527)
  • ModelContextProtocol 0.4.0-preview.1 -> 1.4.1 (Bump ModelContextProtocol from 0.4.0-preview.1 to 1.4.1 #528)

Dependabot grouping update (optimistic grouping)

Updated .github/dependabot.yml to group all NuGet dependencies into a single group:

groups:
  nuget-all:
    patterns:
      - "*"

This is intentionally broad to minimize the number of Dependabot PRs by grouping as much as possible.

Validation

• dotnet build "Part 2 - Project Creation/GenAiLab/GenAiLab.sln" -c Release (pass)
• dotnet build "Part 7 - MCP Server Basics/MyMcpServer/MyMcpServer.csproj" -c Release (pass)
