Avoid narrowing conversion by using operator<< for string output

Replace calls to write() with operator<< when writing std::string
to streams.

std::string::size() returns an unsigned value (size_t), while
std::ostream::write() expects a signed std::streamsize, which
introduces a narrowing conversion.  Using operator<< is simpler,
idiomatic, and avoids this type mismatch.  It also improves
readability without changing behavior.
