chenyue404/GboardHook ? reverse-engineered prompt

I want a small Android tool that hooks into Gboard and changes how the clipboard behaves.

It should let me control how many copied items show up in the clipboard history, and also how long they stay before expiring. If there are a couple of hidden settings that affect clipboard reading, just turn those off for now like the current project seems to do, and make the app work reliably with that approach.

Please keep it simple and practical, with a basic screen where I can see and change the clipboard count and expiration time, then apply the changes. If anything depends on current Android or Gboard behavior, look up the latest docs online if you need to. I mainly want this to work as a straightforward tweak for Gboard clipboard history, not a big complicated app.
