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.

# generate_sankey_chart — 桑基图
## 功能概述
展示资源、能量或用户流在不同节点之间的流向与数量,适合预算分配、流量路径、能耗分布等。
## 输入字段
### 必填
- `data`: array<object>,每条记录包含 `source`string`target`string`value`number
### 可选
- `nodeAlign`: string默认 `center`,可选 `left`/`right`/`justify`/`center`
- `style.backgroundColor`: string设置背景色。
- `style.palette`: string[],定义节点配色。
- `style.texture`: string默认 `default`,可选 `default`/`rough`
- `theme`: string默认 `default`,可选 `default`/`academy`/`dark`
- `width`: number默认 `600`
- `height`: number默认 `400`
- `title`: string默认空字符串。
## 使用建议
节点名称保持唯一,避免过多交叉;如存在环路需先打平为阶段流向;可按阈值过滤小流量以聚焦重点。
## 返回结果
- 返回桑基图 URL并在 `_meta.spec` 存放节点与流量定义。
