What & Why

PR #9028 ("fix(designer): Default agent connection type to MicrosoftFoundry") removed AzureOpenAI from the agentModelType dropdown options in the agent loop manifest (agentloop.ts) and changed the default to MicrosoftFoundry.

This restores AzureOpenAI ("Azure OpenAI") as a selectable agent model source. The default remains MicrosoftFoundry — only the option was re-added, not the default.

Note: AzureOpenAI was only ever removed from the dropdown. The x-ms-input-dependencies visibility rules and the connection/serialization logic already continue to handle 'AzureOpenAI' (see the existing values: ['AzureOpenAI', 'MicrosoftFoundry'] entries throughout the manifest), so no other changes are needed.

Impact of Change

• Users: Azure OpenAI is once again available in the "Agent model source" dropdown when configuring an agent. New agents still default to Foundry Models.
• Developers: No API changes.
• System: No architecture, performance, or dependency changes.

Test Plan

• Unit tests added/updated
• E2E tests added/updated
• Manual testing completed
• Tested in: Standalone designer — confirm "Azure OpenAI" appears in the Agent model source dropdown
