We'll get things to dynamically work with stdin and stdout and allow reusing Docker Compose commands when a TTY is available.

When running Docker Compose commands in CI environments, the error 'the input device is not a TTY' occurs because Docker Compose tries to allocate a TTY by default. The fix is to use the `-T` or `--no-tty` flag. A practical shell script pattern dynamically detects TTY availability by checking file descriptors 0 (stdin) and 1 (stdout) using `[ -t 0 ]` and `[ -t 1 ]`, then conditionally sets the `-T` flag. This allows the same run script commands to work both locally (with TTY) and in CI pipelines (without TTY), including piped input scenarios like importing database dumps.
