/**
* Executes a command and captures its output.
*
* This function spawns a child process, collects its stdout and stderr, and resolves with the
* process result when execution finishes. By default, it throws an {@link ExecError} when the
* process exits with a non-zero exit code.
*
* @param _command - The command to execute.
* @param args - The arguments passed to the command.
* @param options - The options object.
* @param options.signal - An optional AbortSignal used to abort the process.
* @param options.timeout - An optional timeout in milliseconds. When provided, the
* process is aborted after the timeout expires.
* @param options.stdin - An optional string written to the process stdin.
* @param options.spawnOptions - Additional options forwarded to `child_process.spawn`.
* @param options.throwOnNonZeroExitCode - Whether to throw an {@link ExecError} when the
* process exits with a non-zero exit code. Defaults to `true`.
* @returns A promise that resolves with the process result.
* @throws {ExecError} Throws when `throwOnNonZeroExitCode` is enabled and the process exits with a
* non-zero exit code.
*
* @example
* const result = await exec('echo', ['hello']);
*
* console.log(result.stdout.trim());
* // => 'hello'
*
* @example
* const result = await exec('git', ['diff', '--quiet'], {
*   throwOnNonZeroExitCode: false,
* });
*
* console.log(result.exitCode);
* // => 1 when there are changes
