/*
 * gz.c - zlib inflate/deflate wrappers driving a malloc-grown output
 * buffer. Both functions consume the entire input in one go (one-shot
 * codec, no streaming). Output buffer doubles when full; that bounds
 * realloc count to log2(out_size).

File::Raw's plugin chain. Put C<'gzip'> first in a READ and WRITE chains

    # READ:  bytes -> inflate -> csv parse
    my $rows = file_slurp("data.csv.gz",
                          plugin => ['gzip', 'csv']);

    # WRITE: csv encode -> deflate -> bytes
    file_spew("out.csv.gz", $rows,
              plugin => ['gzip', 'csv']);

C<each_line> (the streaming path) is single-plugin only; chain
composition belongs to the slurp/spew/append/atomic_spew calls.
