TFormula: Render LaTeX from any CLI app directly in Kitty-compatible terminals

I've originally asked for it two weeks ago on the Ghostty github discussions page [1], and it turns out someone decided to just go ahead and develop it. It looks awesome. What's most stunning to me is that back in the 90s and 00s we would have waited several years to someone try and attempt something like this. Huge thanks to GH user mikewang817

P.S. I changed "agent" to "app" in the title since that makes much more sense. I think the author used the wrong word there. Maybe tformula was initially meant for only agents and then it turned out to work for all CLI apps and the title hasn't been updated yet.
