Detect GitHub Copilot app in CLI telemetry

[Damian Edwards (DamianEdwards)]

Description

The Aspire CLI does not currently identify commands run from the GitHub Copilot app separately from the underlying Copilot CLI. This keeps CodingAgentDetector aligned with the latest detection rules in dotnet/sdk.

When AI_AGENT=github_copilot_app_agent is present, telemetry now reports copilot-app. The Copilot app also sets COPILOT_CLI, so its complete coding-agent value is copilot-cli, copilot-app.

Validation:

dotnet test --project tests\Aspire.Cli.Tests\Aspire.Cli.Tests.csproj --no-launch-profile -- --filter-method "*.CodingAgentDetector_DetectsKnownCodingAgents" --filter-not-trait "quarantined=true" --filter-not-trait "outerloop=true"

📝 Documentation has been drafted in microsoft/aspire.dev#1589 targeting release/13.6.

Added a 13.6 data-points row to the Microsoft-collected CLI telemetry doc noting that the CLI now separately reports copilot-app for the GitHub Copilot desktop app (detected via AI_AGENT=github_copilot_app_agent), alongside the existing copilot-cli value.
