fix: Dev to main PR

[Dhruvkumar-Microsoft]

Purpose

This pull request adds and enforces a strict policy to suppress citation markers and attribution in agent responses, particularly for agents using a knowledge base. It also updates tests to ensure these new instructions are correctly applied. The main changes are grouped below:

Knowledge Base Citation Suppression:

• Added a _KNOWLEDGE_BASE_NO_CITATIONS_PROMPT string to agent_factory.py that instructs agents not to include any citation markers, source-reference tokens, attribution markers, or footnotes in their responses.
• Updated create_agent_from_config in agent_factory.py to append the no-citations prompt to agent instructions when a knowledge base is configured.

Prompt and Helper Updates:

• Added the no-citations instruction to the final answer prompt in get_magentic_prompt_kwargs to ensure plan review summaries also suppress citations.

Testing Enhancements:

• Mocked KnowledgeBaseConfig in test setup and ensured agent objects support use_knowledge_base and knowledge_base_name fields. [1] [2] [3]
• Added and extended tests in test_agent_factory.py to verify that knowledge-base-backed agents receive the new citation suppression instructions. [1] [2]
• Added a test in test_plan_review_helpers.py to confirm that final prompts suppress citations as intended.

Pull request overview

This pull request enforces a “no citations / no attribution markers” response policy for knowledge-base-backed agents and for the orchestrator’s final answer prompt, and updates unit tests to validate the new prompt behavior.

Changes:

• Added a KB-specific “RESPONSE CITATION POLICY” prompt segment and appended it to agent instructions when a knowledge base is configured.
• Updated the orchestrator final-answer prompt rules to suppress citation/attribution markers.
• Expanded unit tests to cover KB config wiring and to assert the citation-suppression policy is present in generated prompts.
