//! Per-core actor runtime for Ursula.
//!
//! Module map:
//!
//! - [`cold_store`]: opendal-backed cold tier handle and object path helpers.
//! - [`request`]: HTTP/gRPC request and response value types for each engine op.
//! - [`command`]: the replicated [`GroupWriteCommand`] envelope around the
//!   canonical [`ursula_stream::StreamCommand`], plus `From` conversions from
//!   request values into that command.
//! - [`error`]: runtime-level error type [`RuntimeError`].
//! - [`engine`]: the `GroupEngine` trait, factory, metrics, and the boxed-future
//!   type aliases that form the replaceable per-group engine boundary, plus the
//!   in-memory implementation under [`engine::in_memory`].
//! - [`runtime`]: `ShardRuntime`, `RuntimeConfig`, and per-core worker spawn.
//! - [`core_worker`]: single-thread actor that owns groups for one core.
//! - [`group_actor`]: per-group mailbox actor running inside a core worker.
//! - [`ops`]: declarative manifest of the uniform runtime operations; expands
//!   into the per-operation actor and client plumbing.
//! - [`metrics`]: runtime metrics shared across cores; lock-free counters.
