## Summary This PR enhances the time series query execution framework to properly propagate and expose query exceptions instead of throwing them, enabling better error handling and reporting for both broker-compatible and Prometheus-compatible APIs. This enables partial results with warnings instead of complete failures, as well as exceptions from leaf operators visible at the broker level. The exceptions are encoded in the `metadataMap` passed alongside data, and stored in `TimeSeriesBlock` for upward propagation. To support partial results for Prometheus-compatible API, this PR also introduces a `warnings` field (as specified in the [Prometheus API reference](https://prometheus.io/docs/prometheus/latest/querying/api/)) to expose these warnings correctly. ## Testing Added integration test `testQueryWithServerException` to verify exception handling for both response formats: - Broker-compatible API: validates exceptions are properly returned with error codes. - Prometheus-compatible API: validates warnings are included in success responses. -- This is an automated message from the Apache Git Service.
