dsh-skill-hub: Managing DeepSeek Harness Skills in dsh Web

dsh-skill-hub is a dsh web plugin (MIT licensed) developed by cheshireez, designed to centrally manage scattered skill catalogs. It runs based on the official SDK and slot without modifying the dsh source code, primarily addressing issues such as difficulty in skill retrieval, scattered enable/disable entry points, lack of diagnostics, inconsistent import processes, and missing invocation statistics. Core features include: browsing and searching the complete `ctx.skills` catalog on the settings page; supporting enable/disable and body viewing for individual skills or groups; diagnosing frontmatter issues in `SKILL.md`; supporting new skill scaffolding; tracking source repositories and commits for import, synchronization, and recycle bin recovery; scanning and importing marketplace skills from built-in or custom repositories; and counting invocations based on session logs.
