feat: add TweetClaw social intel skill

[kriptoburak]

Summary

• Add an optional TweetClaw social-intelligence skill for X/Twitter buying-signal research and prospect enrichment.
• Wire the optional workflow into lead discovery, heartbeat checks, SDR rules, and tool guidance.
• Keep social writes, monitors, webhooks, extractions, and persistent actions owner-approved.
• Use the current verified ClawHub install source and document the closed-source hosted Xquik boundary.

Independent Repository Fix

The root SKILL.md declared MIT-0, but the repository LICENSE, package.json, and GitHub license detection all identify MIT. This repair changes the skill metadata to MIT so installers and catalogues receive the repository’s actual license.

Validation

• git diff --check
• npm test
• bash -n deploy/skill-profiles.sh
• changed skill frontmatter checks
• secret-pattern scan across every changed file
• TweetClaw npm metadata verified at v1.6.37, MIT, with clawhub:@xquik/tweetclaw as the default source
• public commit signature verified by GitHub

Xquik Boundary

TweetClaw is MIT-licensed. It connects to Xquik, a closed-source hosted service operated independently from X Corp. Xquik is not affiliated with or endorsed by X Corp.

Rebuilt this PR on current main as 1 signed commit.

The optional TweetClaw workflow now uses the current ClawHub install source, preserves owner approval for writes and persistent operations, and states that the hosted Xquik service is closed source and independent from X Corp.

I also fixed an independent metadata defect: root SKILL.md said MIT-0, while LICENSE, package.json, and GitHub all report MIT. The metadata now matches the repository license.

npm test, shell parsing, frontmatter checks, secret scanning, npm metadata verification, and public signature verification pass.
