v0.6.6a1

Added

• BROWSER_NO_SANDBOX config option
  New BROWSER_NO_SANDBOX: bool | None setting controls Chrome's sandbox mode.
  Defaults to None (auto-detect): sandbox is disabled automatically when the process runs
  as root on Linux (e.g. Zyte, Docker). Set True to force no-sandbox, False to keep
  sandbox even as root. Configurable via settings.py (BROWSER_NO_SANDBOX = True) or
  the config object.

Fixed

• Browser engine fails on Docker (running as root)
  Chrome refuses to start without --no-sandbox when the process is root. The engine now
  auto-detects root and adds both --no-sandbox and --disable-dev-shm-usage (required
  in containers with limited /dev/shm).

• headless=False crashes in display-less environments
  When no $DISPLAY is set on Linux (Docker, CI), the engine now silently overrides
  headless=False to headless=True, preventing Chrome from crashing on startup.
