`bun repl` exits with no error message if `/tmp` is mounted `noexec`

[190n]

What version of Bun is running?

1.3.5+1e86cebd7

What platform is your computer?

Linux 6.12.15-production+truenas x86_64 unknown

What steps can reproduce the bug?

Run bun repl on a system where /tmp is mounted with noexec (in my case TrueNAS Scale)

What is the expected behavior?

It should work, or at the minimum it should show what went wrong like exec /tmp/bunx-1000-bun-repl@latest/node_modules/.bin/bun-repl: Permission denied

What do you see instead?

$ bun repl
$ echo $?
1
