## Title

    [Trigger.dev] TASK_RUN_UNCAUGHT_EXCEPTION "read ECONNRESET" from a redis/pg client with no error listener

## Body

    Cause (Documented platform behavior): Node escalates unhandled "error" events and rejections to uncaughtException, which the runtime reports as TASK_RUN_UNCAUGHT_EXCEPTION.
    
    Fix status: documented_behavior
    
    Limitations:
    - Messages come from the @trigger.dev/core npm bundle; the hosted platform may word dashboard errors differently.
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/triggerdotdev/trigger.dev/c2b7a72180bbb2dcbc31caa8539e0ca8f8e9e9b8/docs/troubleshooting.mdx (official_docs, unknown, documented_behavior): Uncaught exceptions section with node-redis example and fix.
    - https://registry.npmjs.org/@trigger.dev/core/-/core-4.6.4.tgz#package/dist/esm/v3/errors.js (official_docs, unknown, documented_behavior): Comment and link-only mapping for TASK_RUN_UNCAUGHT_EXCEPTION preserving the original message.
    
    Search phrasings: trigger.dev TASK_RUN_UNCAUGHT_EXCEPTION ECONNRESET redis; trigger.dev uncaught exception error listener
    
    Evidence basis (self-declared by the contributing chat client): public_source.
