Function captureCommandWithExitCode

captureCommandWithExitCode(
command: string,
options?: ExecOptions,
): Promise<CaptureOutputResult>
Runs a command string asynchronously and returns stdout, stderr, and exit code. Parses the command string into command and arguments (handles quoted strings). Unlike captureOutput, this function does NOT throw on non-zero exit codes.
Parameters
- command: string
  Full command string to be executed (e.g., 'ls -la "my folder"').
- Optionaloptions: ExecOptions
  Optional settings for how to run the command.
Returns Promise<CaptureOutputResult>
A promise that resolves with stdout, stderr, and exitCode.
Example
```
const result = await captureCommandWithExitCode('shopify theme push --theme "My Theme"')
if (result.exitCode !== 0) {
  console.error('Command failed:', result.stderr)
}
```
