Upgrade GitHub Copilot SDK to 1.0.11-preview.2

[SIkebe]

Summary

• Upgrade GitHub.Copilot.SDK from 1.0.10-preview.0 to 1.0.11-preview.2 to stay aligned with the latest preview runtime and rewind protocol.
• Synchronize release packaging with the SDK package's bundled Copilot CLI 1.0.79, including the official Windows x64 and ARM64 SHA-256 values, and update the third-party notice.
• Explicitly keep session file-change tracking disabled until RepoSyncRadar provides a user-visible rewind flow. The current radar tools do not edit workspace files, so enabling tracking would add unnecessary state and monitoring overhead.
• Audit the official SDK release, rewind implementation in #2321, and the Java/Node-only changes in #2301 and #2309. The NuGet package points to commit 5c2dec4; dependencies and MSBuild target behavior are unchanged.

The target package's generated props pins CLI 1.0.79, not 1.0.79-6, so the release asset version and hashes intentionally follow that package contract.

Related Issues

N/A - no issue to close

Scope

• App UI / workflow
• Core services / data model
• Copilot SDK / agent behavior
• Preview / WebView2
• Documentation / release readiness
• Tests / tooling
• Other:

Validation

• dotnet build RepoSyncRadar.sln -warnaserror
• dotnet test RepoSyncRadar.sln --timeout 10m -- --filter-not-trait Category=Manual (1,039 passed)
• N/A - focused behavior is covered by the full solution test run
• N/A - no UI/WebView changes

Risk And Rollback

• User impact: Copilot sessions use the updated SDK and bundled CLI while preserving the existing no-file-tracking behavior.
• Operational risk: Low. This is a preview dependency update, but the package dependencies and build targets are unchanged and the full automated suite passes.
• Rollback plan: Revert this commit to restore SDK 1.0.10-preview.0, CLI release 1.0.79-6, and the prior checksums.

Release Notes

• User-facing change
• Internal-only change
• No release note needed

Release note draft:

N/A - internal dependency and runtime compatibility update.
