JeffJiang 4d5fdcb8db Consolidates market and data analysis skills; adds chart viz (#36)
Unifies market analysis, data analysis, and consulting reporting into a comprehensive consulting-analysis skill, enabling a two-phase workflow from analysis framework design to professional report generation. Introduces a DuckDB-based data analysis utility for Excel/CSV files and a chart-visualization skill with a flexible JS interface and extensive chart type documentation. Removes the legacy market analysis skill to streamline report generation and improve extensibility for consulting and data-driven workflows.

- `data`: array<object>,每条至少含 `category`string`value`number如需分组或堆叠需补充 `group`string
### 可选
- `group`: boolean默认 `true`,用于按系列并排展示不同 `group`,开启时需确保 `stack=false` 且数据包含 `group`
- `stack`: boolean默认 `false`,用于将不同 `group` 堆叠到同一柱子,开启时需确保 `group=false` 且数据包含 `group`
- `style.backgroundColor`: string自定义背景色。

当类别较多(>12时可按 Top-N 或聚合;堆叠模式要确保各记录都含 `group` 字段以免校验失败。
