//! Module: text_value
//!
//! Responsibility: select Query's plain-table, optional-value and truncation policies.
//! Does not own: mechanical escaping, table alignment, JSON serialization or process output.
//! Boundary: delegates escaping/layout to Host while keeping report presentation choices local.
