New Features
Auto-annotate option: Automatically annotate pages when they load — configurable in Settings.

Bug Fixes
Race condition on toggle: Fixed an issue where toggling annotation while it was still in progress could leave the page in a partially annotated state.
Firefox text extraction: Worked around Firefox bug 1976237 affecting text node extraction.
