// DSL parsing and expansion utilities for query/system/observer macros.
//
// This module provides a declarative syntax for building Flecs queries, systems, and observers.
// The DSL is parsed into structured types and then expanded into the appropriate builder calls.
//
// Module structure:
// - `types`: Core types like Reference, Access, TermIdent, TermOper
// - `term`: Term-related structures (TermId, Term, TermType)
// - `parser`: DSL parser and builder structures (Dsl, Builder, Observer)
// - `ident_expander`: Functions for expanding TermIdent into builder calls
// - `builder`: High-level builder call generation logic
// - `expansion`: Common expansion utilities (traversal, term types)
// - `query`: Query-specific expansion logic
// - `system`: System-specific expansion logic
// - `observer`: Observer-specific expansion logic
