kernel/builtins/test262: 本批新码 clippy 三则 + fmt 归净——obfuscated_if_else（source_escape_to_key 值域判定改 if/else）、needless_range_loop（decode_uri_units 保留字符原样段改 extend_from_slice）、needless_borrows_for_generic_args（844f2f4 rename 调用两处冗余借用）；fmt 漂移（compiler.rs/vm.rs 构造体折行）一并归净。七 crate clippy 零告警、fmt --check 净、七 crate 2879/1（唯一失败 compile_class_declaration 既有）、release 子集 8/8 + 2/2 终验
