Package the repo as an Agent Plugin (v1.0.0)

The skills/ layout already matched the spec, so this only adds the two
manifests: plugin.json at the root and mcp.json mirroring .mcp.json with
explicit stdio transports. Both validate against the published schemas.

.mcp.json stays for Claude Code — the migration is additive, not a move.

README: document plugin installation, and add ai-sdk-7 and hetzner-cloud,
which shipped without a table entry.

+### As an Agent Plugin
+
+This repo is an [Agent Plugins v1.0.0](https://agent-plugins.org/) package: [`plugin.json`](plugin.json)
+at the root, skills as immediate children of `skills/`, and MCP servers in [`mcp.json`](mcp.json).
+Clone it and point a plugin-capable client at the folder:
+
+```bash
+git clone https://github.com/laguagu/claude-code-nextjs-skills.git
+```
+
+Loading a plugin is client-specific — installation, enablement and updates are deliberately
+[outside the spec](https://github.com/agentplugins/agent-plugins-spec/blob/main/spec/1.0.0.md),
+so check your client's docs (ChatGPT, Codex, Cursor, GitHub Copilot, VS Code and Kiro all
+support the format). What the spec does guarantee is that every one of them reads the same
+`skills/` and `mcp.json` — no per-client rearranging.

+Two files carry this, on purpose: [`mcp.json`](mcp.json) is the portable Agent Plugins copy that any
+plugin-capable client reads, and [`.mcp.json`](.mcp.json) is the Claude Code project file. Both wire up
