AWS lambda documentation change
Summary
Added references to Lambda durable functions as code-first alternatives throughout Step Functions documentation, including comparisons and specific feature links.
Security assessment
Changes focus on workflow orchestration alternatives without mentioning security vulnerabilities, encryption, access controls, or threat mitigation. The additions are purely about feature comparisons between Step Functions and Lambda durable functions.
