Subject: [PATCH] fix: add lib accessors so examples compile

basic_usage.rs and mlp_router.rs called methods that didn't exist on the
public API (8x E0599). Add thin 1:1 accessor/convenience wrappers:

- Orchestrator::current_project() -> delegates to context manager
- MLP::input_size() / MLP::output_size() -> getters for private fields
- MLP::train_step() -> backward + update, returns the step loss

cargo check --examples is now clean (lib was already fine).
