docs: merge Dev v3 into main

[Vamshi-Microsoft]

Purpose

This pull request introduces several important updates to deployment requirements, workflow configuration, and agent behavior, as well as a minor frontend style change. The most significant changes are the enforcement of a minimum Azure Developer CLI (azd) version, enhanced instructions and validation in deployment workflows, and stricter output formatting for retail agents.

Deployment requirements and documentation:

• Updated all documentation (README.md, docs/DeploymentGuide.md) and the azure.yaml configuration to require Azure Developer CLI (azd) version 1.18.0 or higher, replacing the previous minimum version and adding clear upgrade/download instructions. [1] [2] [3] [4]

Workflow and security improvements:

• Enhanced the Azure template validation workflow (.github/workflows/azure-dev.yml) by adding a production environment, using secret-based credentials, enabling additional validation options, and improving output handling and documentation for each step.

Agent behavior and compliance:

• Strengthened the system_message for both CustomerDataAgent and OrderDataAgent in data/agent_teams/retail.json, adding explicit instructions to avoid all forms of citations, source references, or attribution markers in responses, ensuring clean and compliant output. [1] [2]

Frontend style adjustment:

• Adjusted the .tab class in TeamSelector.module.css to use a negative margin, likely to refine tab alignment or spacing in the UI.

Does this introduce a breaking change?

• Yes
• No
