v4.0.12 — OpenClaw scanner: fix documentation/bundle mismatch

## What changed

The OpenClaw scanner correctly identified a documentation/bundle mismatch introduced in earlier versions. This release fixes all three root causes:

### Fixed

- **`skill.json` runtime mismatch** — `runtime` changed from `"node"` to `"python"`; `entrypoint` changed from `"index.ts"` to `"scripts/swarm_guard.py"`. The SKILL.md instructions only call Python scripts — the Node/TS claim was incorrect.
- **`node` listed as required binary** — removed from `requires.bins` in SKILL.md. Moved to `optional_bins` with an explicit note: only needed if the user separately installs the npm MCP server (`npm install -g network-ai`). It does not run automatically.
- **Description implied full Node.js ecosystem is bundled** — `skill.json` description rewritten to accurately describe the Python-based local orchestrator. The Node.js MCP server is now explicitly called out as a separate optional npm package (`network-ai`) that is not part of this skill bundle and is not auto-fetched.
- **`install` block restructured** — Python scripts listed as `bundled / instruction-only` (nothing downloaded at install time). Node MCP server moved to `optional_node_server` key with a clear "must be installed manually" note.
- **SKILL.md scope notice** — added a prominent block at the top of the instructions section stating: Python-only execution, no automatic network calls, Node server is a separate opt-in component.

### Summary: what this skill does

All SKILL.md instructions run local Python scripts (`scripts/*.py`).  
No network calls are made by the bundled skill.  
The Node.js MCP server (`npx network-ai-server`) is a **separate optional component** — install with `npm install -g network-ai` only if you want MCP/IDE integration.

### Installation

```bash
# Python skill (this bundle — no install step required)
# Use via OpenClaw / ClawHub directly

# Optional: Node.js MCP server (separate component)
npm install -g network-ai
npx network-ai-server --port 3001
