WriteString failures were silently discarded, so a failed write (e.g. disk full) still exited successfully. outputItems now returns the error, output propagates it to main, which reports it and exits non-zero. Adds unit tests covering the write path and the error propagation.

Returning early on the first write error left producers blocked on the unbuffered outputchan while main waited for all goroutines, deadlocking the command. writeOutput now records the first error and keeps draining until the channel closes, returning the recorded error afterwards. Adds a regression test for the drain behavior and reports file close errors in tests.

Close errors were swallowed by the deferred f.Close in output. The file is now closed explicitly after writing: close failures are reported when the write succeeded, while the write error stays authoritative when both fail.
