Find the repository root by searching for .atomic directory. Starts at the given path and walks up to parent directories until a `.atomic` directory is found that contains `pristine.redb` (indicating it's a repository, not just a config directory like `~/.atomic/`). The search stops at the user's home directory to prevent accidentally treating the entire home directory as a repository.
