Experiment: move PWD and Git info from shell prompt to tmux pane titles

I'm just trying this on for size for now but it looks pretty:

https://eseth.org/2019/tmux-status-line.html

Pros:

- It reduces a bit of CLI clutter and gives a single, stable place to
  look for certain info.
- You can see infos even when running full-screen CLI programs.

Cons:

- You lose a bit of contextual info when scrolling through the
  scrollback since you can't see the current directory or current Git
  hash next to the command you typed. In practice I haven't really
  missed it so far.
- Tmux does not wait for external commands to finish before drawing the
  UI so in order to view changes in near real-time this requires a fair
  bit of Zsh machinery to manually tell tmux to refresh after changing
  directories or running Git commands.
