Subject: [PATCH] docs(setup): persist the TinyTeX PATH in the shell profile on
 macOS (#609)

The TinyTeX snippet exports PATH for the current session only. A new terminal
window then fails with 'command not found: lualatex' although the install worked.
Add the persisted form and a one-line check.

+The `export` above only lasts for the current terminal window. Persist it, or every new window reports `zsh: command not found: lualatex` (or `xelatex`) even though TinyTeX installed fine:
+
+```bash
+echo 'export PATH="$HOME/Library/TinyTeX/bin/universal-darwin:$PATH"' >> ~/.zshrc
+source ~/.zshrc
+lualatex --version   # should print a version, not "command not found"
+```
+
+(Bash users: append to `~/.bash_profile` instead.)

 Then install the template dependencies:
 
 ```bash
