[dotnet-port-api] Add tool approval bypass opt-out

[github-actions]

Summary

Port the public opt-out from microsoft/agent-framework#6970 for bypassing approval requests on tools that do not actually require approval.

This adds toolapproval.Config.DisableNonApprovalRequiredToolBypassing, wires it into the middleware's auto-approval decision path, adds focused coverage for the opt-out behavior, and updates the .NET/Go feature comparison note to reflect the exposed Go surface.

Upstream source commit: 76f2c1a0c974cd4168857dc71520597674650bf8 (https://github.com/microsoft/agent-framework/commit/76f2c1a0c974cd4168857dc71520597674650bf8).

Ported .NET PRs

• .NET: [BREAKING] Graduate per-service-call persistence and approval-not-required function bypassing agent-framework#6970 - graduate per-service-call persistence and approval-not-required function bypassing

Breaking Changes

No.

Tests and Examples

• go test ./agent/harness/toolapproval ./agent/harness/toolautocall -count=1
• Added focused toolapproval coverage verifying that queued non-approval-required tool requests are surfaced when bypassing is disabled.
• Updated docs/dotnet-go-sdk-feature-comparison.md
• No examples changed; this port adds a configuration opt-out to existing middleware behavior rather than a new end-user scenario.

Notes

• The other public change in upstream PR #6970 (RequirePerServiceCallChatHistoryPersistence) is a broader chat-client pipeline feature and was intentionally not bundled into this narrow nightly port.
• Existing Go behavior already matched the default bypass semantics; this PR only exposes the public opt-out needed for parity.
