fix: prevent unhandled promise rejection when done() throws

Add .catch(safeReject) to pendingDones promises so that errors from
done() (e.g. invalid output schema) are caught instead of becoming
unhandled promise rejections that crash the process.

In develop, these errors are caught by the worker message handler's
try/catch → reject(). With pendingDones pattern, the promise could
reject after the exit handler already resolved, causing a crash.
