zackandGitHub 8fdaa5a2d3 feat: add extension_paths parameter for loading Chrome extensions (#210)
Add `extension_paths` parameter to all launch functions (Python + JS) for loading Chrome extensions.

Resolves paths to absolute, injects `--load-extension` and `--disable-extensions-except` flags via `build_args()`.

Note: Extensions require a persistent context (`launch_persistent_context`) to function — this is a Chromium limitation.
