    • [OPIK-7454] fix: bound trace-thread online-scoring span preload to stop heap OOM

    • [OPIK-7454] fix: enforce the span-preload cap in UTF-8 bytes; reuse traceIds

    Baz review follow-ups:

    • C6/C7: the heap cap compared a UTF-16 char count against a byte-denominated
      cap, so non-ASCII payloads could exceed the intended limit. Add
      JsonUtils.getSerializedLengthInBytes (streaming UTF-8 count via
      CountingOutputStream) and use it in BoundedSpanAccumulator, so the cap and the
      ClickHouse size aggregate are both UTF-8 bytes. The token estimate keeps the
      char-based getSerializedLength (unchanged; also feeds trace-level scoring).
    • C5: reuse the already-computed traceIds for the attachment lookup instead of
      re-streaming traces.
    • Tests: JsonUtilsTest covers the byte variant incl. a non-ASCII case where the
      byte count exceeds the char count.
