Stop executing subsequent tasks and &&-chained commands when any task exits with non-zero status. Previously, all tasks would run regardless of failures. Now the runner stops immediately, matching shell && semantics for chained commands and providing faster feedback on errors. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Stop running tasks after a failure, instead of continuing with the rest.
Two cases:
buildin package A fails, don't bother runningbuildin package B that depends on it.&&— if a script iseslint . && vitest run, andeslintfails, don't runvitest.Previously both cases would keep going regardless of failures. Now the runner stops at the first failure and exits with that task's exit code.
