Suggestion: Inline semi-transparent prediction instead of side list

[andreyeh]

Thank you for developing this extension. I just love it.

Currently, FluentTyper shows suggestions as a list next to the word I am typing. My suggestion is to instead (or optionally) display the prediction inline, directly on the same line I am typing, using a gray semi-transparent style (similar to Gmail and GitHub Copilot). It may reduce visual distraction and boost typing speed for some people like me.

Thanks again for your work on this extension!
