feat: remove hardcoded 256 symbol limit and switch to dynamic symbol table with 16-bit instruction arguments

Browse Source 
Replace the fixed-size MAX_SYMBOLS array with a dynamically growing StringBuffer for symbol names, update all instruction encodings to use 16-bit operands for constants and method symbols, and refactor method binding to use a dynamic MethodBuffer per class. Remove the constant deduplication logic in addConstant and the commented-out struct fields in initCompiler.
