lib/stringsutil: optimize AppendLowercase

The optimization includes the following improvements:
- Implementation of a function that processes 8 bytes per loop iteration to locate ASCII characters using bitwise manipulations.
- Implementation of the ToLowercaseFunc function that prevents string copying if the string is already in lowercase.
- Use of a lookup table for converting ASCII characters to lowercase, with logic copied from the VictoriaLogs repository.

Choose the source depending on the use case.

 In today's fast-paced and complex landscape of system monitoring, [VictoriaMetrics Anomaly Detection](https://victoriametrics.com/products/enterprise/anomaly-detection/) (`vmanomaly`), a part of our [Enterprise offering](https://victoriametrics.com/products/enterprise/), serves as an **observability layer** for SREs and DevOps teams atop of collected data to **automate the detection of anomalies in time-series data**, reducing manual efforts required to identify abnormal system behavior.
 
-Unlike traditional threshold-based alerting, which relies on **raw metric values** and requires constant tuning and maintenance of thresholds and alerting rules, `vmanomaly` introduces a **unified, interpretable [anomaly score](https://docs.victoriametrics.com/anomaly-detection/faq/#what-is-anomaly-score)** - a **de-trended, de-seasonalized metric** generated through machine learning. This approach eliminates the need for frequent manual adjustments by enabling **stable, long-term static thresholds (as simple as `anomaly_score > 1`)** that remain effective over time through continuous model retraining and updates.

 ## What does it do?
 
-`vmanomaly` is designed to **periodically analyze new data points** across selected metrics - either requested from [VictoriaMetrics TSDB](https://docs.victoriametrics.com/victoriametrics/) or produced by [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/) or [VictoriaTraces](https://docs.victoriametrics.com/victoriatraces/) metrics [endpoint](https://docs.victoriametrics.com/victorialogs/querying/#querying-log-range-stats) - to generate a **unified metric** called [anomaly score](https://docs.victoriametrics.com/anomaly-detection/faq/#what-is-anomaly-score).
-
-> [!NOTE]
-> `vmanomaly` can use both single-node and cluster versions of VictoriaMetrics/VictoriaLogs/VictoriaTraces as a data source, and is compatible with both OpenSource and Enterprise versions of it. However, `vmanomaly` itself requires an Enterprise license to run, and is part of our [Enterprise offering](https://victoriametrics.com/products/enterprise/).

 ## Changelog
 
-### v1.6.1
-Released: 2026-04-16
-
-vmanomaly version: [v1.29.3](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1293)
-
-- IMPROVEMENT: Consecutive anomalies (when "streaks" option is enabled) are now grouped in the Visualization Panel as a single anomaly line instead of multiple dots for reduced visual noise and better representation of prolonged anomalous periods, while still showing the exact anomaly score and labels on hover.
-
-- IMPROVEMENT: Raw query results now refresh automatically after time range changes; yet anomaly detection results are preserved until "Detect Anomalies" button is hit again, to avoid recalculating anomalies on the new time range without explicit user action, which could be costly if the new time range is large and the model is complex.
-
-- IMPROVEMENT: Table legend view is now enabled by default for sorting and filtering enablement.
-
-- BUGFIX: Generated config and example alert outputs now preserve configured fit/infer values correctly and avoid invalid float-based duration strings in generated YAML, which could lead to data validation errors if copied to production configuration without adjustments.
-
-- BUGFIX: Fixed multiple confusing anomaly UI behaviors around scheduler fields (fit_every, infer_every) and generated artifacts.
-
-- BUGFIX: Chart y-axis range is now updating after legend series selection (regression introduced in v1.6.0).
