feat: add kyberforge plugin and rename plugin-create skill

Scaffolds the kyberforge marketplace management plugin (create-plugin and
marketplace-architect skills will live here). Renames the plugin-create
skill directory to create-plugin to match the canonical kebab-order convention.

+Agent definitions for this plugin. Each agent needs two files — one per tool:
+
+| File | Tool | Notes |
+|---|---|---|
+| `<name>.md` | Claude Code | Frontmatter: `name`, `description`. No `tools:` field. |
+| `<name>.agent.md` | GitHub Copilot CLI | Frontmatter: `name`, `description`, `tools:` (array of permitted tool names). |
+
+The two files share the same system prompt body. Keep them in sync.
+
+Rename `PLUGIN_NAME.md` and `PLUGIN_NAME.agent.md` to your agent's name (kebab-case).
+Add additional agent pairs as needed — one pair per agent.

+
+To add a skill, run `/write-skill` in a Claude Code session. Do not write SKILL.md by hand
+without following the authoring standard — trigger descriptions and self-checks are required.
