Upgrade Squad.Agents.AI Copilot SDK and MAF bridge

[tamirdresher]

Summary

• upgrade Microsoft.Agents.AI.GitHub.Copilot from 1.14.0-rc1 to 1.15.0-rc1
• keep GitHub.Copilot.SDK pinned at 1.0.8
• apply _MicrosoftAgentsAICopilotSdkVersion to the package project too so every build path resolves the same Copilot SDK / CLI payload

Why

PR #1449 previously tried to bump GitHub.Copilot.SDK from 1.0.3 to 1.0.5, but the build broke when the Copilot client packaging changed and the MAF bridge still resolved the stale SDK floor.

This retry is now unblocked because Squad.Agents.AI already has the explicit SDK bridge/override pattern from the later fix, and moving the MAF adapter forward to 1.15.0-rc1 still works as long as that override is applied consistently.

Validation

• dotnet test Squad.Agents.AI.slnx -c Release
• packed local nupkg + ran scripts/verify-squad-agents-ai-consumer.ps1
  • verified a real PackageReference consumer gets Copilot CLI 1.0.73
  • confirmed no fallback to stale CLI 1.0.67
• sample smoke test:
  • dotnet run --project src/Squad.Agents.AI/samples/Squad.Agents.AI.Sample/Squad.Agents.AI.Sample.csproj -c Release --no-build -- --flow=1
  • sample booted, created the agent, and reached the first SDK call successfully

Target repo

Confirmed from git remote -v, gh repo view, and existing PR history that the correct upstream target is bradygaster/squad against dev.

Pull request overview

This PR upgrades the Squad.Agents.AI .NET package’s Microsoft Agent Framework Copilot adapter dependency, pins GitHub.Copilot.SDK via a single repo-wide property, and adds both build-time and CI-time guards to ensure the correct Copilot CLI/native payload propagates to transitive consumers (including real external NuGet consumers).

Changes:

• Bump Microsoft.Agents.AI.GitHub.Copilot to 1.15.0-rc1 and make GitHub.Copilot.SDK version come from $(SquadCopilotSdkVersion).
• Add a pack-time generated buildTransitive/Squad.Agents.AI.props bridge to force _MicrosoftAgentsAICopilotSdkVersion for external consumers.
• Add a hermetic consumer verification PowerShell script and CI steps to detect stale/mismatched Copilot CLI payload downloads.

Superseded by #1602 which cherry-picks this PR's meaningful changes (Directory.Build.props condition removal + comment updates) onto current dev. The .csproj version bumps were already superseded by dependabot updates on dev (1.16.0, Extensions 10.8.3/10.0.10). Thank you @tamirdresher!
