refactor, platform extensions and app

[alex2awesome]

I made the following changes:

New features:

• A standalone app that will run for users who are not familiar with command-line. It will guide them through the permissions needed to run the app on their computer (only on apple so far).
• App and browser URL tracking (if the user is on a browser) for all events so we have more of a trace of what they were doing.
• Apple-specific logging on MacOS (for increase speed) with a Pynput fallback if the apple logging doesn't exist or won't work

Refactor:

• I tried to separate the functionality well into different files and provide a bit of a template for expanding
• cli/ and app/ are separate folders and they each try to handle as little functionality as possible. The only things they handle are basically:
  • Functionality of the different usage
  • Where things run: the CLI runs everything in the background. app/macos needs to run keyboard tracking in the foreground for security concerns.
• gum/ orchestrates the events, locks and semafors to make sure the users events are all getting logged in order (I think it was an error I observed in earlier versions, but I could be wrong)
• observers/ now handles most of the meat of the actual tracking. I included a blank folder for windows expansion and other platform expansion as need be, going forward.

Please give it a quick scan. I can do more work to make it a bit more legible. There were a few parts that I vibe coded out of frustration when the keyboard tracking wasn't working (😭) and some of the more cross-browser URL checking.
