//! `include:` directive — merging externally included compose files.
//!
//! Included files are merged into the parent: services, volumes, networks,
//! secrets, and configs from the included file are added only if the key does
//! not already exist in the parent (parent wins on conflict).

/// Merge `other` into `target`.
///
/// Services / volumes / networks / secrets / configs from `other` are added;
/// existing entries in `target` win on conflict (parent file overrides included content).
