Summary

Track enabling the ext-azure-ai-agents-live pipeline to be manually queued from GitHub PR comments for relevant azure.ai.agents changes.

Context

The live Tier 2 pipeline runs against real Azure resources, so it should not be part of automatic PR validation. However, Azure Pipelines requires a PR trigger association before /azp run ... comments can queue a pipeline.

Expected outcome

• The live pipeline is associated only with relevant PRs targeting main.
• ADO requires a team member comment before building PRs.
• /azp run azure-dev - live - ext - azure.ai.agents queues definition 8268 from a matching PR.
