+Added `x-security` extension for Respect that enables secure handling of authentication in workflows.
+This extension allows you to:
+
+- Define security schemes at the step level using either predefined schemes or inline definitions
+- Pass secrets values (passwords, tokens, API keys)
+- Support multiple authentication types including:
+  - API Key (query, header, or cookie)
+  - Basic authentication
+  - Bearer token
+  - Digest authentication
+  - OAuth2
+  - OpenID connect
+- Automatically transform security parameters into appropriate HTTP headers or query parameters
