🤖 Fix ENOENT error in todo_write for SSH runtimes

Ensure temp directory exists before writing todos.json. Previously,
writeTodos() assumed the directory already existed, but SSH runtime
initialization could fail to create it, resulting in ENOENT errors.

Added fs.mkdir() with recursive: true to create the directory if needed.
