+/**
+* 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
