feat: add createLexerAndParser helper for unified error listening#87
Merged
Conversation
Adds a new ApexParserFactory.createLexerAndParser(source, listener) helper in both the TS and Java packages. It attaches the required ApexErrorListener to both the lexer and the parser so a single listener instance captures lexer-level errors (e.g. invalid string escapes) as well as parser errors. The TS ApexErrorListener base class generic is widened to `Token | number` so one listener can be attached to both recognizers. Closes #83
