Added typing indicator block via injection

[zeyadhost]

What's this?

Adds a proper typing indicator blocker by injecting a small payload into Discord's index.js.

What changed

• Created typing_blocker.py which handles finding Discord's install folder on Windows and macOS and injects the JavaScript needed to block the typing indicator.
• The blocker is controlled by a simple flag file (.ghost_silent_typing). You can toggle it on/off from chat and it takes effect immediately with no restart needed.

Note

The users cannot see any type of typing indicator, but for the person who is going to use this (you), you'll still be able to see the typing indicator which is next to your avatar in the member's list:

How to test

1. Run .st in any channel (if it's your first time, it'll inject and ask you to restart Discord.)
2. Restart Discord.
3. Type in any channel and the indicator shouldn't be triggered.
4. Run .st again to toggle it off.

Currently not working on macOS. Potentially the script that's injected into index.js needs to be different for macOS? I will do some testing as seems like fun idea. I also want to attempt this without injecting into the client.
