duyanta123/dsh-data-insight: DSH Data Insight Skill Plugin

`duyanta123/dsh-data-insight` is a data insight skill plugin based on the DSH ecosystem, designed to transform CSV files, pasted tables, SQL query results, or DuckDB data into structured Markdown reports containing business conclusions, metrics, and charts. The plugin adopts a purely instruction-based implementation with zero dependencies and zero build steps, utilizing an LLM to drive the host tool for calculations. Its core functionality encompasses support for five data sources and a five-stage pipeline—ranging from "Input Processing, Data Exploration, Metric Calculation, Chart Visualization, to Report Generation." It provides metrics such as summary statistics, month-over-month (MoM) and quarter-over-quarter (CoM) comparisons, TopN rankings, and anomaly detection, and supports three chart visualization formats: Markdown, Mermaid, and ASCII. Users can install the plugin via the `dsh plugin` command and initiate analysis directly within a session.
