v0.6.5

Fixed

• patch_nodriver() now safe to run multiple times
  The previous implementation used importlib.util.find_spec("nodriver.cdp.network") which
  itself triggered the SyntaxError it was trying to fix (importing the submodule requires
  importing the parent, which fails). Switched to find_spec("nodriver") (top-level only)
  and constructing the path to cdp/network.py via pathlib. Additionally, the replacement
  now uses a regex negative lookbehind (?<!\xc2)\xb1 to prevent double-encoding on
  subsequent runs.

• Browser engine: handle tab/browser closed mid-request
  Two new exception types are now caught and raised as StealthConnectionError instead of
  logging as unhandled errors:

  • ConnectionClosedError — WebSocket dropped (tab closed while loading)
  • ProtocolException — CDP target no longer found (tab/context destroyed)
