LibTmux::Workspace::X::Load::report_data

For Load exceptions, return a detached, JSON-safe report hashref. The primary cause and each cleanup error become records with class, message, known path, and dispatched (null means unknown). Core creation/load causes retain their cause chain; a repeated exception is marked cycle. Process results retain exit code, signal, raw wait status, and bounded stdout and stderr as stdout_base64 and stderr_base64 using MIME::Base64. This diagnostic encoding does not serialize entity graphs or arbitrary exception internals. Other exceptions retain their class and string message. No I/O occurs; editing the export cannot change "report" or "cause".

    use JSON::PP ();
    my $data = $error->report_data;
    say JSON::PP->new->canonical->encode($data);
