Multi-Channel Skill Publisher

Publish ONE skill to ALL agent-skill channels from a single source of truth: the ClawHub skill registry, a ClawHub bundle-plugin package, and a Claude Code plugin marketplace (plain GitHub repo). Use when the user wants to publish, release, rename, or version-bump a skill/plugin across registries, or asks how to package a skill as a Claude Code plugin or OpenClaw bundle plugin. Covers the SSOT/sync model against redundancy, exact manifests (plugin.json, marketplace.json, openclaw.plugin.json), known CLI bugs and their web-UI workarounds (rename, --name, display-name fallback), versioning pitfa
