Apply the same __restrict__ local pointer pattern proven in encode_varint_raw_64 to all remaining methods that write through pos_: encode_varint_raw, encode_varint_raw_short, write_raw_byte, encode_raw, write_tag_and_fixed32, encode_string, encode_bool, and encode_fixed32. Each method now hoists pos_ into a __restrict__ local before writing and stores back once at the end. When the compiler inlines these into a generated encode() method, it can keep pos_ in a register across consecutive calls instead of reloading from memory after every write.
