Log entries with large string fields (e.g. HTTP response bodies) were
exceeding Grafana Loki's 256KB per-entry limit and being dropped.
Instead of truncating and losing data, oversized string fields are now
automatically split across multiple log entries, each annotated with
chunk metadata ({key}_chunk, {key}_total_chunks) for reassembly.
