runtimo-daemon 0.7.2

//! Daemon configuration: data directory, socket path, WAL path resolution.
//!
//! Provides default path resolution for the daemon's runtime data directory,
//! Unix socket, and write-ahead log. All paths can be overridden via
//! environment variables (`XDG_DATA_HOME`, `RUNTIMO_WAL_PATH`).
//!
//! # Ownership
//! Owns path resolution and data directory lifecycle.
//!
//! # Dependencies
//! - `runtimo_core::utils` for `data_dir()` and `wal_path()` base resolution.
