[azsdk-cli] Investigate prompt understanding approach for azsdk tools

See https://github.com/awslabs/mcp/blob/main/src/core-mcp-server/awslabs/core_mcp_server/static/PROMPT_UNDERSTANDING.md as an example approach. This could help with tool list overload and selection consistency.

Start by reading the linked PROMPT_UNDERSTANDING.md example from the AWS MCP repository, then inspect the azsdk tools context relevant to tool-list overload and selection consistency. The work is done when the approach has been evaluated for azsdk tools and the resulting direction is documented.
