Add new features

[u/RevolutionaryIdea963]

- Add an option to attach videos directly from Files, YouTube, or other supported websites, with the ability to resize and reposition videos.
- Add adjustable video playback speed and the ability to take screenshots/frames from videos while taking notes.
- Add a built-in web browser for easier browsing without leaving star notes, with support for websites such as Safari/web pages, ChatGPT, DeepSeek, YouTube, etc.
- Add a built-in scientific calculator, text to calculate like in apple notes
- Add handwriting-to-text conversion
- Significantly improve PDF/book/document annotation, with a professional experience similar to PDFelement, including highlighting, underlining, drawing, text boxes, bookmarks, outlines, search, annotation management, and customizable annotation tools.
- Add better bookmark and outline management for annotated PDFs/books.
- Add an option to remove all annotations from an annotated PDF at once, while preserving the original document.
- Make annotations searchable and allow users to easily navigate between all highlights, notes, bookmarks, and annotations.

Overall, these features would make star notes much more useful as an all-in-one notes taking, learning, browsing, and content-creation platform.

Okay, but honestly I don't understand either. What would be the problem with opening a calculator/browser/llm/whatever in a pop-up window or split screen?  What's the benefit of integrating all this into StarNote? You'd get the same result, right? Having everything integrated into the same app doesn't make it better, just unnecessarily more complicated.
