Issue #57545
Fixes a buffer overflow issue when flushing Redis cache tags with large numbers of keys (5000+). The flush operation now chunks keys into batches of 1000 instead of trying to send them all at once.
Laravel already handles this correctly for clustered connections by chunking keys. This just applies the same fix to non-clustered connections.
