dsh-web-recorder: DSH Browser Action and Network Request Recorder

`dsh-web-recorder` is a DeepSeek Harness (DSH) plugin designed to address the problem of missing or outdated documentation for API integration. It records browser operations and network requests, generating a Markdown summary and a raw event stream that help large models analyze and infer API call sequences and data formats. The plugin supports attaching to an already open browser or launching a headed browser, and provides the `recorder_start`, `recorder_stop`, and `recorder_status` tools to make business workflows explicit and systematically capture them through action trails.
