BREAKING CHANGE(taskbuffer): Change default Task error handling: trigger() now rejects when taskFunction throws; add catchErrors option (default false) to preserve previous swallow behavior; track errors (lastError, errorCount) and expose them in metadata; improve error propagation and logging across runners, chains, parallels and debounced tasks; add tests and documentation for new behavior.
