Add TweetClaw evidence collection to brand monitoring

[kriptoburak]

Summary

• Extend the existing brand-impersonation skill with an optional TweetClaw evidence path.
• Discover current tool routes before collection instead of hard-coding endpoint names.
• Preserve canonical account and post identifiers in a reviewable source packet.
• Keep correlation, risk scoring, escalation, and takedown decisions in the existing skill.
• Require separate approval for private reads, recurring workflows, webhooks, and writes.
• Remove the unrelated README badge from the original proposal and bump the skill to 1.1.

Verification

• python3 tools/validate-skill.py --all passes all 817 skills.
• Targeted skill validation passes.
• git diff --check upstream/main...HEAD

Conflict repair pushed in b6c3eee.

What changed:

• merged current upstream main
• resolved the README framework-section conflict by keeping the new MITRE F3 section
• fixed the README framework anchor and AI RMF URL that failed link validation during the merge

Validation:

• strict conflict-marker scan on README and the touched brand-monitoring skill
• git diff --check
• npx --yes markdown-link-check README.md skills/performing-brand-monitoring-for-impersonation/SKILL.md --quiet

Rebuilt on current main as f8f4652 (GitHub-verified SSH signature). The PR is now conflict-free and mergeable.

Validation completed locally:

• all 817 skills pass the repository validator
• no duplicate names across 817 skills
• the updated skill's links pass
• TweetClaw, Xquik docs/dashboard, NHS page/badge, and the replacement NIST page return HTTP 200
• the old NIST URL returns 404, and the repaired Frameworks anchor now targets the live heading

GitHub Actions shows action_required and created no jobs. This is the fork workflow approval gate; a maintainer must approve the run before the repository workflow can execute. No failed check is currently available for contributor repair.

Rebased onto current main and narrowed this to the existing impersonation workflow. The unrelated README badge is gone. TweetClaw only supplies approved public evidence; the skill retains correlation, risk scoring, escalation, and takedown ownership. It discovers live routes, preserves canonical IDs, and gates private or persistent actions. All 817 skill validations pass.
