application-level retry logic.

=head1 CALLBACK LIFETIMES

Callbacks are stored in C structures that are invisible to Perl's garbage
collector. A callback closure that captures the client (or its own stream
handle) forms a reference cycle that Perl cannot reclaim: the objects stay
alive until the stream is cancelled or the client is destroyed, even if all
Perl-side references are dropped.

For long-lived streams, capture a weakened client reference and call
C<cancel()> when the stream is no longer needed:

    use Scalar::Util 'weaken';

    my $client = EV::Etcd->new(endpoints => ['127.0.0.1:2379']);
    weaken(my $weak = $client);
    my $watch = $client->watch('/my/key', sub {
        my ($resp, $err) = @_;
        return if $err;
        $weak->put('/my/seen', 1, sub {}) if $weak;
    });
    # ... later:
    $watch->cancel(sub { });
