docs: add TweetClaw and repair workflow index

[kriptoburak]

Summary

• Add TweetClaw as an optional X/Twitter monitoring plugin.
• Run installation inside the stack's OpenClaw container.
• Allow both current TweetClaw tools and restart the service.
• Link the canonical credential configuration guide.
• Add the required independent-service disclosure.
• Fix the workflow table so every listed filename exists.

Independent Repository Fix

The workflow table named 4 files that were not present. It now lists the 2 actual importable workflow exports with accurate descriptions.

Validation

• Parsed every workflow JSON file with jq.
• Verified exact README-to-directory filename parity.
• Verified both commands against TweetClaw's canonical README.
• Verified the Docker Compose service name.
• Checked all edited external links.
• Ran git diff --check.

The branch contains 1 GitHub-verified signed commit on current main.

Repair commit 48f6fb2 is public and GitHub-verified.

I narrowed the PR to the workflow-index repair and TweetClaw setup. The instructions now execute inside this stack's OpenClaw container, allow both current tools, restart the service, and link the canonical credential guide.

Every workflow JSON parses. The README index exactly matches the workflow directory. Both TweetClaw commands match its canonical guide. The Docker service, edited links, and whitespace checks also pass.

The PR is 1 signed commit on current main and ready for maintainer review.
