    Merge branch 'issue_5601': scoped-trace builder package + port aggregations

    Merges the telemetryscopedtraces refactor (generic scoped-trace topology moved
    out of telemetryai, feature-flagged gen_ai key enrichment, tracefield. context
    classification) and ports the scalar/time-series work onto it:

    - trace_aggregation.go / trace_having.go now live in telemetryscopedtraces
    - trace-level HAVING resolution composes the canonical pkg/variables
      replacement (dynamic __all__ drops a condition for any operator) with the
      standard filter pipeline, so values still bind as args
    - buildPerTraceScan adopts the merged embedExpr placeholder/arg checking
    - ColumnProvider gains ActivityGateAlias; gen_ai provider gates trace-level
      aggregations on llm_call_count

    feat: trace-level aggregations for scalar/time-series and trace-scoped span list

    - trace.-prefixed aggregations (avg(trace.output_tokens), count(trace.trace_id),
      arithmetic) run over window-clipped per-trace values via a native CTE pipeline
    - a trace-level filter condition qualifies traces in scalar/time-series/raw via
      __qualified / __trace_scope, resource-fingerprint pruned like the trace list
    - trace-level filter conditions resolve through the standard filter pipeline
      (bound args, operators, query variables) against the per-trace column aliases
    - per-trace rows with no LLM span in the window are dropped from trace-level
      aggregations (LLM-activity gate)
    - targeted rejections for group-by/order-by on trace-level columns
