DeepSeek Harness SMS Webhook Plugin

`huaxiren6/dsh-sms-webhook` is an SMS forwarding plugin for DeepSeek Harness. It listens on a local port to receive SMS messages (such as verification codes), stores the data in JSONL format, and provides the `sms_recent` and `sms_search` tools for model queries. It supports keyword filtering, automatic truncation (5,000 entries), and field aliases. It is easy to install and suitable for developers whose local agents need to read SMS messages, but security risks should be considered.
