dsh-compliancehub: DeepSeek Harness Remote Provider for Cross-Border Compliance Skills

DSH ComplianceHub is a remote compliance skills provider plugin maintained by wwumit. It uses the `ctx.skills` mechanism to allow DeepSeek Harness (DSH) to load cross-border compliance skills (such as GDPR/CCPA) directly from a remote JSON catalog, eliminating manual file operations. The plugin provides `list` and `get` interfaces with fault-tolerance support. Installation depends on an npm package, and enabling it requires specifying catalogUrl. Known limitations include retrieving only the body of SKILL.md, no catalog caching, and no support for private catalogs.
