Perl

Not a particularly hard task, but converting all tests is a lot of work. We want to go from:

# Promisify
is ref Mojo::Promise->resolve('foo'), 'Mojo::Promise', 'right class';
$promise = Mojo::Promise->reject('foo');
is ref $promise, 'Mojo::Promise', 'right class';
@errors = ();
$promise->catch(sub { push @errors, @_ })->wait;
is_deeply \@errors, ['foo'], 'promise rejected';
$promi

im kinda of a perfectionist, so i tends to collect every piece of metadata i could find.
unfortunately one of them is the "Summary" which currently there's no easy way to add it.

i think adding a "Summary" field that supports multi-line text would truly make lanraragi a more complete archival.
