dsh-foundry: DSH Plugin Blueprint Compiler

dsh-foundry is a self-bootstrapping plugin compiler for DeepSeek Harness (DSH), designed to simplify plugin development. It is itself a DSH plugin that encodes runtime contracts into blueprints, supports one-click generation of directly definable host/browser code, and performs static validation before definition. Core capabilities include providing a foundry service for other plugins to invoke and extend recipes, built-in blueprints covering nine scenarios such as Host, Client, and RPC, and three model tools: foundry_blueprints, foundry_scaffold, and foundry_validate. Installation requires manual linking via package.json and configuring bundles, followed by running pnpm i.
