Crate graphforge_ast 

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
