Hi!
How can I add row to a matrix?
⟨ ⟨ 1 | 2 ⟩ | ⟨ 3 | 4 ⟩ ⟩ ⟨ 5 |6 ⟩ J → ⟨ ⟨ 1 | 2 ⟩ | ⟨ 3 | 4 ⟩ | 5 | 6 ⟩
⟨ ⟨ 1 | 2 ⟩ | ⟨ 3 | 4 ⟩ ⟩ ⟨ 5 |6 ⟩ W → ⟨ ⟨ ⟨ 1 | 2 ⟩ | ⟨ 3 | 4 ⟩ ⟩ | ⟨ 5 | 6 ⟩ ⟩
but i need ⟨ ⟨ 1 | 2 ⟩ | ⟨ 3 | 4 ⟩ | ⟨ 5 | 6 ⟩ ⟩

@user How easy would it be to have an sbt command to spin up a server (on a specific port, like 6942), that listens for API requests to run Vyxal code?

My idea is that we could use my online Vyxal interpreter for development, so that it would keep recompiling, and you could just press run and it would use your latest development build, without having to wait for `fastOptJS` to run.
