@abapify/acds

Parser for ABAP CDS DDL source (.acds/DDLS sources). Tokenizes, parses, and produces a typed AST for tables, structures, simple types, services, metadata extensions, and (phased) roles + view entities. Built on chevrotain with error recovery — partial ASTs plus structured errors are returned even on malformed input.
