Support for iOS via LiteRT-LM (C++ implementation)

[nesror]

According to the official LiteRT-LM (formerly MediaPipe LLM Inference) documentation, the iOS implementation is currently available through the C++ API (https://ai.google.dev/edge/litert-lm/cpp).

Given this, I have a few questions regarding the roadmap for iOS support:

Are there any plans to begin iOS adaptation using the existing C++ version?

Or is the project's strategy to wait for the official Swift APIs to be released before starting the iOS implementation?

Working on native LiteRT-LM support for iOS via FFI (C++ API). This will bypass the MediaPipe executor and use the C++ LiteRT-LM SDK directly — fixing the .litertlm crashes on iOS and enabling full feature parity with Android/Desktop.

Closing as duplicate of #218 — tracking both the crash fix and native iOS LiteRT-LM support there.
