`src/engine.rs` — the engine module root

The re-export root for the whole engine: pub use bare::*; pub use core::*; — so loopctl::engine::{BareLoop, RunConfig, Loop, ...} all resolve from here.

Key items

• engine::BareLoop — the driver (from bare).
• engine::core::{Loop, Run, Session, Turn, RunConfig, TurnMode, LoopMachine, MachineState, MachineStep, MachineOutcome, MachinePolicy} (from core).

Behavior notes

• Two namespaces behind one door: engine::core holds the brain-side types, engine::bare the driver — most user code imports from engine directly and never notices.

Deep dives: state machine · driver. Sibling root: engine-core.md.
