tool-bash and tool-pwsh no longer render their own background reads. processSources() wraps the process's observed offset readers as registry pull sources, pumped at dsh-jobs-local's pumpPollMs, and processOutcome() folds the settled sandbox facts into the terminal detail. observe.ts and the recordPollMs config field are gone; READMEs and pairings follow.
