Updating examples with conversation history

[steven10a]

• Adding guidance to dev's on conversation history best practices. I.e, don't store user message until guardrails have passed
• Updated all examples with this best practice
• Added a brief section in the quickstart.md to explain this
• Removed stage_name being passed in through the config (dead code no longer used)

Pull Request Overview

This PR updates examples and documentation to implement conversation history best practices, specifically ensuring user messages are only added to conversation history after guardrails pass. The changes also remove deprecated stage_name configuration that is no longer used.

Key changes:

• All examples now pass user input inline without mutating message history first
• Message history is only updated after guardrail validation succeeds
• Documentation added to explain this pattern and why it prevents blocked messages from polluting context
