//! Task queue task-level operations.
//!
//! Purpose:
//! - Task queue task-level operations.
//!
//! Responsibilities:
//! - Mutate or query tasks within queue files (complete tasks, set statuses/fields, find tasks, delete tasks, sort by priority).
//! - Provide typed domain errors for queue query operations to enable stable test assertions.
//!
//! Non-scope:
//! - Persisting queue data or managing locks (load/save/locks/repair live in `crate::queue`).
//! - Task-level validation beyond runnability checks (see `validate` module for schema-level validation).
//!
//!
//! Usage:
//! - Used through the crate module tree or integration test harness.
//!
//! Invariants/assumptions:
//! - Queue operations are called with fully loaded `QueueFile` values.
//! - Queue query errors are returned as `anyhow::Result` but wrap typed `QueueQueryError` for downcasting in tests.
//! - Message text in `QueueQueryError` variants must match user-facing expectations (single source of truth).
