+//! Complete FFI wrapper for the age encryption library.
+//!
+//! Provides C-compatible functions for all age encryption operations:
+//! - Key generation (x25519, SSH)
+//! - Encryption/decryption (memory and file-based)
+//! - Passphrase-based encryption (scrypt)
+//! - ASCII armor support
+//! - Multiple recipients support
