Satisfies the PhoenixClient JSON-parser contract, which requires encode/2, encode!/2, decode/2, decode!/2 and encode_to_iodata!. The optional opts argument is accepted but intentionally ignored so that this module can be dropped in wherever a standard JSON library is expected.

Updates endpoint.ex to use this serializer.

Binary Frame Support

In addition to text-based TOON encoding, this serializer supports compact binary frames for Phoenix.Socket.Message, Phoenix.Socket.Broadcast, and Phoenix.Socket.Reply structs. Binary frames use a length-prefixed binary protocol that avoids the overhead of text serialization.

• fastlane!/1 — Binary-encoded broadcasts (Phoenix.Socket.Broadcast with {:binary, data} payload)
• encode!/1 — Binary-encoded replies and messages with {:binary, data} payloads
• decode!/2 — Decodes both text and binary frames (pass opcode: :text or opcode: :binary)

Note: This is a workround for avoid add Phoenix library dependency.
