docs: add TweetClaw X action handoff

[kriptoburak]

Summary

• Add a current CLI-based CreatorCrawl workflow for reviewed X/Twitter action handoff through TweetClaw and OpenClaw.
• Preserve CreatorCrawl as the structured research source and keep TweetClaw as a separate, approval-gated action companion.
• Publish the workflow through both the source skill and .well-known distribution.
• Repair pre-existing drift where 5 public .well-known workflow files no longer matched their current source files.
• Add a manifest-driven validator and GitHub Actions check that enforce exact source, public mirror, and file-list parity.

Closes #1.

Validation

• node --check scripts/validate-skill-mirror.mjs
• node scripts/validate-skill-mirror.mjs
• Parsed .github/workflows/validate-skill-mirror.yml
• Byte-compared both SKILL files and every mirrored workflow
• Validated the .well-known/skills/index.json file list
• git diff --check
• Current-base merge-tree check

Published current-upstream repair 7609d9bacb58f9949bbbcb6c5f97af74e2bbbb81 as 1 signed commit.

This preserves the reviewed CreatorCrawl to TweetClaw handoff and fixes an independent distribution defect: 5 .well-known workflow files had drifted from their source counterparts. The manifest-driven validator now enforces source-tree, public-mirror, file-list, and byte-level parity in CI.

Validation passed for JavaScript syntax, JSON parsing, workflow YAML parsing, exact mirror parity, live Xquik links, canonical npm package metadata, whitespace, and the current upstream diff. No contributor action remains.
