Add stealth mode for Chrome headless to evade bot detection

Implements comprehensive anti-detection measures:
- Override navigator.webdriver to return undefined
- Inject fake chrome.runtime, chrome.loadTimes, chrome.csi objects
- Add realistic plugins and mimeTypes arrays
- Patch permissions API to hide automation
- Set realistic navigator properties (languages, hardwareConcurrency, deviceMemory)
- Remove ChromeDriver-specific window properties (cdc_*)
- Patch Function.prototype.toString to hide modifications
- Add Chrome flags: --disable-blink-features=AutomationControlled
- Set realistic user-agent without HeadlessChrome identifier
- Exclude 'enable-automation' switch

Tested against bot detection sites:
- bot.sannysoft.com: All major tests pass
- Search engines: Works with DuckDuckGo, Yahoo, Brave, Startpage
- Still detected by: Google reCAPTCHA, Cloudflare Turnstile, Bing
