Consolidate seven pending NuGet dependency updates

[Copilot]

Updates all seven packages to the requested versions without downgrades or unrelated changes. Supersedes Dependabot PRs #124, #126, #127, and #133.

• Azure Functions
  • SignalRService: 1.13.0 → 2.1.0
  • EventGrid extension: 3.3.0 → 3.5.0
  • ThisAssembly.Project: 1.3.1 → 2.1.2
• Testing
  • Microsoft.NET.Test.Sdk: 17.9.0 → 17.13.0
  • xunit: 2.5.0 → 2.9.3
  • xunit.runner.visualstudio: 2.5.0 → 3.0.2
• CLI
  • CliWrap: 3.6.6 → 3.10.2
• Outstanding compatibility blocker
  • All 27 tests pass, but solution restore fails with NU1605: the Azure updates require Microsoft.Extensions.DependencyInjection >= 8.0.1, conflicting with the explicit 6.0.0 reference. Updating that additional package awaits approval.

• Fixes Bump all open dependency updates together #134

@copilot restore fails. Please bump the direct Microsoft.Extensions.DependencyInjection reference in src/FunctionApp to 8.0.1 or later (upward only, never downgrade) so restore succeeds. Version changes only; no product code or public API changes.

Fixed in 15cb7b0: bumped the direct Microsoft.Extensions.DependencyInjection reference from 6.0.0 to 8.0.1. Restore, Debug/Release builds, all 27 tests, and formatting checks pass. Only the package version changed; no product code or public API changes.

@copilot The build now fails with NuGetizer NG0012 duplicate pack files in src/EventGrid/EventGrid.csproj (the per-platform jq/jq.exe copies and System.Text.Encodings.Web.dll under tools/net6.0/any). Please add a small packing fix, like devlooped/dotnet-tor#123 did with a PreserveToolPackageSubdirectories target, so those files are deduplicated or keep their subdirectories. Keep changes limited to build/packaging. If the packing fix doesn't work, drop the bump that causes the duplicates and keep the rest. Never downgrade a package below main.

Fixed in 9013e36 with a project-local PreserveToolPackageSubdirectories target. CI-style packing and standalone pack now succeed; verified all five jq binaries and both encoding assemblies retain distinct package paths. All 27 tests and formatting checks pass. Changes are packaging-only, with all dependency bumps retained.
