feat: add open-claw-skills plugin — 4,957 remote OpenClaw skills

Lightweight plugin that registers a remote_repo provider pointing to
github.com/javimosch/open-claw-skills. On install, the post_install
hook auto-registers the provider. Skills are indexed from GitHub's
Tree API on 'supercli skills sync'.

+
+# open-claw-skills
+
+A remote skill library with 4,957 curated OpenClaw skills, pulled directly from GitHub.
+
+## What's Inside
+
+Skills are sourced from [clawskills.sh](https://clawskills.sh) across 30 categories:
+
+- **Coding Agents & IDEs** (1,162) — Development tools, code editors, CI/CD
+- **Web & Frontend** (902) — Web development, frameworks, design
+- **DevOps & Cloud** (375) — Infrastructure, containers, deployment
+- **Search & Research** (340) — Web search, API discovery
+- **Browser & Automation** (310) — Web automation, scraping
+- **AI & LLMs** (159) — AI model usage, prompt engineering
+- And 24 more categories...
+
+## How It Works
+
+This plugin registers a `remote_repo` provider. On `supercli skills sync`, it fetches the GitHub Tree API to discover all SKILL.md files — no local clone needed.
+
+## Commands
+
+```bash
+# Search skills
+supercli skills search "docker"
+supercli skills search "git"
+
+# Get a specific skill
+supercli skills get open-claw-skills:runeweaverstudios.docker-skill
+
+# List all providers
+supercli skills providers list
+```
