Create a `secure_defaults` tool

[DrewDennison]

New tool that allows models to query what are recommended best practices and secure defaults given a query. Pull the secure defaults from https://github.com/tldrsec/awesome-secure-defaults or similar

method should probably look like:

@mcp.tool
def secure_default(query: str) -> JsonResponse:
    # return a structured data object with a recommended library or framework. 
    # optionally return a semgrep ruleset for that framework to ensure the coding model uses the framework securely
    # example query: "I'm looking for a secure default auth library for flask that uses JWT, recommend me one"
