/**
 * Regex patterns used throughout the grammar
 *
 * Exports actual RegExp objects to avoid double-escaping hell.
 * Use these directly in grammar.js rules (no `new RegExp()` needed).
 *
 * Structural Archetypes:
 * - icon_value: icon + text (priority, story, alias, predecessor, id)
 * - icon_datetime: icon + datetime (completed_date, created_date)
 * - icon_composite: icon + parts (do_date: datetime, duration, recurrence)
 * - icon_list: icon + items (context)
 * - icon_rich_text: icon + text/links (description)
 * - marker_only: just icon (sequential)
