    Class WorkerSession

    WorkerSession manages the lifecycle of a single worker instance.

    Hybrid approach:

    • If workerPool is provided: Use pool's worker (reusable, manual pool cleanup)
    • If workerPool is NOT provided: Create disposable worker (auto-cleanup on dispose)

    Use using syntax for automatic cleanup:

    using session = await WorkerSession.create();
    const records = await sendWorkerMessage(session, { ... });
    // Worker is automatically terminated when leaving scope (if disposable)

    using session = await WorkerSession.create();
    const records = await sendWorkerMessage(session.getWorker(), {
      id: session.getNextRequestId(),
      type: "parseString",
      data: csv,
      options: serializeOptions(options),
    });
    // Worker automatically terminated

    using pool = new WorkerPool({ maxWorkers: 3 });
    using session = await WorkerSession.create({ workerPool: pool });
    const records1 = await sendWorkerMessage(session.getWorker(), { ... });
    const records2 = await sendWorkerMessage(session.getWorker(), { ... });
    // Worker returned to pool, pool cleanup happens when pool disposes
