LibTmux::Workspace::X::Load::report

For Load exceptions, return the partial-load report. It contains created IDs, completed and failed steps, dispatch uncertainty, and cleanup failures. Each cleanup_errors entry contains target (the captured identity), action (kill_session), and error (the original exception). Entries follow rollback attempt order, reversing creation order. An empty array means no cleanup failure was observed. The primary "cause" and secondary exception objects retain their identity. Inspect their dispatched and result fields without parsing prose. No I/O occurs.
