/**
 * The search query language, shared by every search surface: the browser
 * title lane, the server index, and agents.
 *
 * - Words are ANDed: every word must match.
 * - `OR` (uppercase) between words makes them alternatives.
 * - `"quoted text"` is a phrase.
 * - `-word` or `-"phrase"` excludes.
 * - `intitle:word` matches the title only.
 *
 * Pure and dependency-free, so browser code can import it from
 * `@agent-native/core/search-query`.
