dsh-flomo: Integrating DeepSeek Harness with Flomo

`dsh-flomo` is a DeepSeek Harness plugin that connects agents to the Flomo note-taking service. It requires no build step, relies on the `fetch` API built into Node.js 22+, and requires restarting `dsh web` after installation. Users can configure credentials and send memos via the Web settings panel or command-line tools (`flomo_send`, `flomo_config`, and `flomo_status`). Configuration data is stored securely, and Flomo syntax tags are supported. It is designed to help agents capture state and inspiration during conversation flows.
