Terminal.app title

I'm not sure if this is an issue only with my terminal (Terminal.app 2.14 on macOS Sonoma), my shell (zsh 5.9), my termcap or the following recipe:

```justfile
psql *REST:
#!/usr/bin/env sh
set -eou pipefail
#echo -en "\033]0;\a"
export PGAPPNAME="psql[$USER@$(hostname)]"
psql \
-h localhost \
-p 55432 \
-U myuser \
-d mydb \
"$@"
```

... but when running this recipe (with `j psql`, just 1.24.0) the Terminal tab title only says "j" as seen in this screenshot:

I often run different recipes in different tabs and so this isn't quite ideal because I can't tell them apart by the title when they all say "j".

By un-commenting the `echo` line in the above recipe the title becomes much more useful:

I could put this into all my recipes but that's a bit messy and easy to forget. I'm wondering if there's anything that could be done in `just` to make this work better?

Start by reproducing the `psql` recipe with just 1.24.0 in macOS Terminal.app, comparing the default tab title with the version that emits the escape sequence. No implementation file or test is named in the issue; done means establishing whether just can provide a useful recipe-specific title without requiring an `echo` line in every recipe.
