Add OpenClaw plugin evaluation guide

[kriptoburak]

What this PR does

Adds a SkillCompass example guide for reviewing networked OpenClaw plugins before allowing tools, API keys, or private workflows. The guide uses TweetClaw as a concrete OpenClaw plugin example because it covers search tweets, tweet replies, post tweets, follower export, media, direct messages, monitors, webhooks, and giveaway draws.

Why

SkillCompass already explains how it works with adjacent tools. This adds a practical install-gate workflow for OpenClaw users who want to evaluate action-oriented skills before enabling live tools.
