Separate library from CLI concerns: - Add Resolver callback type with Decision/Response structs for all interactive decisions (map/struct, type name, tuple/list, shape unification, shape naming, name collision) - Move terminal I/O (Prompter) from library to cmd/jsonpaths - Add public API: New(), ParseFormat(), Generate(), AutoGenerate() - Add Format type with aliases (ts, py, json-paths, etc.) - Fix godoc comments to match exported function names - Update tests to use scriptedResolver instead of Prompter internals - Update doc.go and README with current API
