Document optional TweetClaw X/Twitter source workflow

[kriptoburak]

Summary

• Add an optional TweetClaw workflow for finding public X/Twitter sources before creating Obsidian cards.
• Document safe boundaries for API keys, raw exports, monitor output, and reviewed tweet links.
• Mirror the guidance in the Chinese README and OpenClaw skill instructions.

Validation

• git diff --check
• /Users/burak/.local/bin/python3.11 -m py_compile scripts/process_share_links.py scripts/run_regression.py
• /Users/burak/.local/bin/python3.11 -m unittest discover -s tests -v
• /Users/burak/.local/bin/python3.11 scripts/run_regression.py --preset github
• curl -fsSIL https://github.com/Xquik-dev/tweetclaw
• npm view @xquik/tweetclaw version --json

Note: the local macOS python3 is 3.9.6 and fails on this repo's dataclass(slots=True) usage. I reran the documented checks with Python 3.11, while the repo CI uses Python 3.13.

Thanks for the PR, @kriptoburak. This was a useful addition. I tightened the safety boundary a bit before merging so TweetClaw stays framed as read-only public source discovery by default, with account-backed or write-like actions requiring explicit user intent and human confirmation.\n\nMerged now. I really appreciate the help, and thanks for bringing your enthusiasm for building and programming into the project.
