v0.5.2 - Unified PageFetcher for Proxy Support

What's Changed

Proxy Support for All Engines

• Refactored all non-headless engines (DuckDuckGo, Brave, Sogou, So360, Wikipedia) to use the unified PageFetcher abstraction
• The -p (proxy) flag now works for all engines, not just headless ones
• Each engine accepts a custom PageFetcher via with_fetcher() / with_http_fetcher()

API Changes

• DuckDuckGo::with_fetcher(fetcher) — inject custom fetcher
• Brave::with_fetcher(fetcher) — inject custom fetcher
• Sogou::with_fetcher(fetcher) — inject custom fetcher
• So360::with_fetcher(fetcher) — inject custom fetcher
• Wikipedia::with_http_fetcher(fetcher) — inject custom HTTP fetcher (JSON API)
• All engines still support ::new() with default fetcher (backward compatible)

Tests

• 267 tests passing (added 5 new with_fetcher tests)

Install

v0.5.1 - Auto Chrome Detection & Headless Default

What's Changed

🚀 Features

• Auto-detect and download Chrome for headless engines — no manual Chrome installation required. The engine automatically finds an existing Chrome/Chromium binary or downloads one on demand.
• Headless mode is now the default — the --headless CLI flag has been removed. Headless browser engines (Baidu, Bing China) are enabled by default. Use --no-default-features at build time to disable.

🧪 Testing & Quality

• Added 44 new unit tests (207 → 251 total), improving code coverage from 88% to 91.15%
• Added justfile with coverage support (just coverage)

📦 Install
