DeepSeek Harness Plugin dsh-wsl-obscura: Controlling the Obscura Headless Browser from WSL

`dsh-wsl-obscura` is an optional plugin for DeepSeek Harness (DSH) that addresses the inability of WSL environments to directly invoke the Windows-compiled Obscura browser. It provides three core tools—`obscura_status`, `obscura_fetch`, and `obscura_mcp_hint`—supporting page text extraction, JavaScript evaluation, and stealth scraping. Installation requires meeting the Obscura build prerequisites and DSH version requirements, and specifying the binary location via a configured path or environment variable. It fills the gap in using a native headless browser under WSL, distinguishing itself from `dsh-wsl-browser`, which is intended for GUI browsers.
