.NET: Bump Azure.AI.Projects to 3.0.0-beta.2

[Roger Barreto (rogerbarreto)]

Motivation & Context

Update the .NET Foundry integration to the latest Azure.AI.Projects preview, 3.0.0-beta.2.

Description & Review Guide

• What are the major changes? Bump the central package version and the explicit versions in the Hosted Steering and Resilient Workflow samples from 3.0.0-beta.1 to 3.0.0-beta.2. Update the matching Foundry package comment.
• What is the impact of these changes? The 156 affected projects resolve Azure.AI.Projects, Azure.AI.Projects.Agents, and Azure.AI.Extensions.OpenAI to 3.0.0-beta.2. No Agent Framework API changes or C# adaptations are needed. Samples independently pinned to 2.1.0-beta.4 retain those pins.
• What do you want reviewers to focus on? Consistency between the central version and the two standalone sample versions.

Related Issue

None. Routine dependency maintenance; no matching open issue or duplicate PR was found.

Contribution Checklist

• All 156 affected projects and their dependencies build in Debug across their declared target frameworks with zero warnings or errors.
• All affected unit tests pass on .NET 10: Foundry 435, Foundry Hosting 464, Declarative Workflows 877. No new tests are needed for the version-only change.
• Formatting passes for the three changed projects in WSL2 Docker using SDK 10.0.303. The SDK was installed from Microsoft's checksum-verified archive because its SDK image tag is unavailable.
• The PR follows the Contribution Guidelines.
• This PR is linked to an issue. The contribution guidelines allow trivial changes without one.
• No duplicate open PR was found.
• This is not a breaking change to Agent Framework. The upstream preview's renamed trace-source members are not used by the repository.

Integration-test projects were built but not executed because they require external services.

Overview

The PR consistently updates the centrally managed Azure.AI.Projects version and the two standalone samples that opt out of central package management, while keeping intentionally isolated older sample pins unchanged. The affected preview API surfaces have focused routing and option-propagation tests, and the repository-wide build matrix covers all declared target frameworks with warnings treated as errors. No publishable Critical, High, or Medium defect was established.

Reviewed the supplied pull-request change set across correctness, security/reliability, architecture, and failure behavior.
No publishable findings remained after source verification for this scope.
