DSH Forge: Standalone Profiles for DeepSeek Harness Plugin Development

DSH Forge is a reproducible, runtime-aware environment for DeepSeek Harness (DSH) plugin development. By establishing an isolated `~/.dsh-forge` Home, a `forge` Profile, and developer Agent Presets, it separates development state from formal configurations, preventing pollution of the daily-used `~/.dsh`. Its core features include locally indexing Harness documentation, source symbols, and interfaces to support rapid retrieval, managing resumable plugin experiments, providing multi-level verification workflows (`quick`, `package`, `full`), and a formal Promotion scaffold.
