Cupshe趋势管理插件

面向自建站的数据分析Chrome扩展，使用站点数据源（初期Mock）。

This is a Chrome extension (version 0.1.0) built with Manifest V3 that serves as a comprehensive trend management and data analysis tool for e-commerce sites. The extension provides real-time product analytics including price, sales metrics, inventory, ratings, conversion rates, and competitor comparisons, all presented through an intuitive interface with interactive visualizations such as sales trend charts, traffic source breakdowns, and audience demographics. Users can access the data through multiple entry points including a floating button that opens a side panel, right-click context menus, or the extension's popup window, while administrators can configure data sources and authentication settings (including Feishu OAuth integration) through the options page. The project is structured with a service worker background script for message handling, content scripts for page injection, and a modular utils system that currently operates in mock mode with sample data but can be easily switched to connect with real API endpoints for production use.
