Removing <code>tmux</code>

Prompted by Brandur’s 15 years later, a day without Tmux, I remembered my own slow removal of tmux from my stack a while back. I was leaving Alacritty for Kitty, whose creator has a distaste for multiplexers in general. I was probably in the sweet spot of tmux users for making this transition, though: I was rarely sshing anywhere, and didn’t have a need (at the time) for persistent sessions. tmux was a glorified window and split manager for me. Now, I have just enough configuration to use Ghostty in a tmuxy way, having ported over my split creation and navigation from Kitty while getting used to Ghostty’s native window management.
