fix #67

Summary of Changes

Hello @samzong, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request delivers a highly requested feature: a site-specific blocklist. This allows users to control where TabBoost's content scripts are active, addressing scenarios where the extension might interfere with native site functionalities. The implementation includes a comprehensive UI for managing blocked sites, intelligent matching logic for various URL patterns, and seamless integration with the extension's lifecycle and storage mechanisms.

Highlights

• Site-Specific Blocklist: Introduced a new feature allowing users to disable TabBoost's content script functionalities on specific websites, preventing conflicts with critical workflows.
• User Interface: Added a dedicated 'Website Blocklist' section under a new 'Advanced Settings' tab in the options page for managing blocked sites. A quick 'Disable/Enable on this site' button is also available in the extension popup.
• Content Script Integration: Content scripts now check the blocklist status early in their lifecycle and abort initialization if the current site is blocked. They also listen for blocklist changes to dynamically adapt.
• Persistent Storage & Matching Logic: The blocklist configuration is stored using chrome.storage.sync for persistence across devices. A new utility module handles pattern normalization, infers match types (domain, wildcard, prefix, regex), and builds matchers to determine if a URL should be bypassed.
• Visual Feedback: The extension's badge icon now displays a '×' on blocked sites, providing immediate visual feedback to the user.

Code Review

This pull request introduces a site-specific blocklist feature, allowing users to disable the extension on certain websites. The implementation includes a new UI in the options page, a quick-disable button in the popup, and leverages sync storage. The design is well-documented, and the core logic is encapsulated in a new siteBlocklist.js utility. My review focuses on the correctness of the matching logic, potential performance improvements, code consistency, and localization accuracy. I've identified a bug in the wildcard matching, a deviation from the design regarding caching, and some areas for code cleanup and consistency improvements.
