fix(autoload): correct generated autoloader blank lines

PHP heredocs drop the newline before the closing marker, so a two-blank-line
fragment must port to "\n\n", not "\n\n\n", and the static initializer needs a
"\n" after the $initializer placeholder. This makes autoload_real.php and
autoload_static.php byte-identical to Composer's output. Rewrite the templates
as raw strings mirroring the PHP heredocs.
