GraphForge AST — syntax-faithful, span-rich parse tree.

The AST is internal to the compiler pipeline. graphforge-cypher produces it; graphforge-ir consumes it. No other crate should depend on this crate directly.

Module layout

• [token] — Token enum and Keyword enum (frozen lexer ABI)
• [parse_error] — ParseError and ParseErrorKind
• [ast] — all AST node types
