- Add configurable batch size to PushService, StreamService, UpdateStreamService - Implement per-batch file container rotation for UpdateStreamService - Each batch creates own file container and pushes immediately (catalog API best practice) - Fix: PushService now respects system property (was hardcoded to DEFAULT_QUEUE_SIZE) - Fix: flushAndPush() guards against null updateStreamService with uploader fallback - Add CONFIGURATION.md and UPGRADE_NOTES.md documentation - Update README.md with configuration section - Add comprehensive tests for batching and rotation behavior Breaking changes: - Default batch size increased from 5MB to 256MB - UpdateStreamService pushes each batch immediately instead of accumulating Fixes reviewer feedback: - PushService now uses getConfiguredBatchSize() instead of DEFAULT_QUEUE_SIZE - StreamDocumentUploadQueue.flushAndPush() now handles null updateStreamService

Summary
Adds configurable batch size support to all push services and implements per-batch file container rotation for UpdateStreamService following Coveo's catalog stream API best practices.
Key Changes
Configurable Batch Size
All services now support custom batch sizes (max: 256MB):
PushService(source, options, maxQueueSize)StreamService(source, options, userAgents, maxQueueSize)UpdateStreamService(source, options, userAgents, maxQueueSize)File Container Rotation (UpdateStreamService)
Each batch now gets its own file container:
This follows the catalog stream API best practices.
Testing
Part 3 of 3 - Split from PR #186
Dependencies: Should merge after #187 and #188
