dsh-quickref: DeepSeek Harness Developer Quick Reference Toolkit

dsh-quickref is a plugin-based development assistant within the DeepSeek Harness (DSH) ecosystem, designed to address developers' pain points when looking up syntax formats and performing data conversions. It provides topic-based quick-reference tables and a variety of practical development tools, including regex testing, JSON validation, timestamp conversion, Base64 encoding and decoding, a Cron generator, and text comparison. To install it, run `dsh plugin --profile web add .` in the repository root directory, avoid using `/tmp` paths, and place `@deepseek-ai/*` dependencies in `peerDependencies`. When publishing to the marketplace, you must declare `dsh.bundle` and ensure `cordis.patch` exists.
