fix(json): propagate JsonFile::encode errors instead of unwrapping

PHP's JsonFile::encode throws a RuntimeException when json_encode fails; the
port swallowed that into an .unwrap() marked TODO(phase-c). Return
anyhow::Result from encode/encode_with_options and propagate at every call
site (print_table and list_repositories become Result-returning to carry it).
