/**
 * Parser for authorizer expressions using Acorn.
 *
 * Parses expressions with implicit auth context:
 * - `model.id === userId`
 * - `hasRole('admin')`
 * - `hasSomeRole(['admin', 'moderator'])`
 * - `model.id === userId || hasRole('admin')`
 * - `exists(model.members, { userId: userId })`
 * - `all(model.tasks, { isCompleted: true })`
 *
 * Uses Acorn to parse as JavaScript, then converts the ESTree AST
 * to our domain-specific AST, rejecting unsupported constructs.
