v0.6.8a1

Added

• Intelligent content wait (_smart_wait)
  The browser engine now detects if a page is a JS challenge, CAPTCHA, or script-heavy stub
  (e.g., Cloudflare, DataDome) and automatically waits for the real content to populate.
  It uses a heuristic based on body length and tag structure to decide whether to wait,
  significantly improving success rates on protected sites while maintaining speed on
  normal pages.
• JS challenge detection (_JS_IS_CHALLENGE)
  A comprehensive JavaScript-based detector that identifies common anti-bot platforms
  (Cloudflare, DataDome, Akamai, Kasada) and challenge states (Ray ID, "Checking your browser")
  by scanning the DOM and window title.
• Randomized browser fingerprinting
  Chrome is now launched with randomized --window-size and --lang arguments selected from
  a curated list of common configurations. This ensures that every browser session (and
  every proxy-rotated request) presents a unique, realistic identity to anti-bot systems.

Changed

• Refactored test cases
  Simplified fetch mocks in tests by removing the unnecessary proxy argument and
  streamlining assertions.

Fixed

• Browser engine — improved response handling
  Integrated _smart_wait into the fetch pipeline, ensuring 2xx responses are fully
  rendered before returning.
