[Copilot]

🟡 Changes recommended

There are a few correctness/robustness issues in the updated code and config (notably a malformed log message and a potentially inconsistent binding redirect entry) that should be addressed before approval.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Updates the agent and test suite to support newer .NET runtimes (notably net10.0) while tightening dependency/versioning rules for “platform packages” (DiagnosticSource and related) to avoid runtime loading issues (startup hook / profiler) and .NET Framework binding problems.

Changes:

• Add net10.0 target frameworks across core libraries, integrations, profiler components, and tests; update CI bootstrap to install .NET 9/10 SDKs.
• Introduce a pack-time verification step to enforce “platform package parity” rules described in Directory.Packages.props.
• Stabilize tests under newer runtimes by explicitly disabling the OpenTelemetry bridge in affected assertions and adding/adjusting tests for net10 behavior.
