camel-cli 0.46.0

//! Compiled-artifact support for `camel compile` (openspec change `cli-compile`).
//!
//! The artifact format appends `payload || manifest || fixed footer` to a copy
//! of the current executable. This module owns the pieces:
//!
//! - [`trailer`] — deterministic EOF trailer codec (exact 68-byte footer).
//! - [`manifest`] — canonical operational manifest embedded next to the payload.
//!
//! The artifact embeds authoring text, never `RouteDefinition` or compiled
//! steps: DSL stays responsible for parsing and interpolation, runtime for
//! lowering and lifecycle.
