Gating: confirm a 2.0-compatible AgentGovernance extension

Gating dependency: 2.0-compatible AgentGovernance extension

Part of #481.

Microsoft.AgentGovernance.Extensions.ModelContextProtocol 4.0.0 is referenced in DotNetMcp/DotNetMcp.csproj and is pinned to the 1.x MCP SDK. It is wired in via WithGovernance(...) in Program.cs.

This is the most likely external blocker for the SDK 2.0 upgrade: the version bump cannot land until a governance package built against SDK 2.0 is available (or governance is made optional/removed for 2.0).

Tasks

• Determine whether a 2.0-compatible Microsoft.AgentGovernance.Extensions.ModelContextProtocol exists (or is planned, with timeline).
• If unavailable, evaluate options: pin behind a feature flag, temporarily disable governance for the 2.0 branch, or find an alternative.
• Record the decision and unblock #481.

Acceptance

• A concrete answer on governance-package compatibility, plus an agreed path that unblocks the version bump (#SUB2).

Start by inspecting DotNetMcp/DotNetMcp.csproj and the WithGovernance(...) wiring in Program.cs. Verify whether Microsoft.AgentGovernance.Extensions.ModelContextProtocol has a 2.0-compatible release or stated timeline, then evaluate the listed fallback options. Done means recording a concrete compatibility decision and an agreed path that unblocks #481.
