fix: patch Rust HKDF to output 16 bytes matching Element Call AES-128
Element Call JS SDK derives 128-bit (16-byte) AES-GCM keys via
deriveKey({name:'AES-GCM', length:128}). The C++ FrameCryptor
allocates a larger derived_key buffer, causing Rust HKDF to
output 32+ bytes — key mismatch with JS.
Patch limits HKDF expand output to 16 bytes. Requires Docker
rebuild (Rust FFI binary change).
