docs: add TweetClaw to social media use case

[kriptoburak]

Summary

• Add TweetClaw to the Creative & Content social media capabilities list.
• Keep the change scoped to the existing Social Media & Content Management use case.
• Mention concrete X/Twitter jobs: tweet search, reply tracking, follower export, and approval-gated posting.

Duplicate Checks

• Searched repository content for TweetClaw, @xquik/tweetclaw, Xquik-dev/tweetclaw, Xquik, xquik, ClawHub, and package/listing URL variants.
• Searched open and closed PRs/issues for the same terms.
• Ran GitHub code search against the repository for the same terms.
• Found no existing TweetClaw mention or prior TweetClaw PR/issue.

Validation

• Ran git diff --check.
• Scanned the touched diff for credential-like values.

No license or contribution files were present, so this stays limited to one capability bullet.

Code Review

This pull request updates the 'Key capabilities' section in categories/creative-content.md to include X/Twitter automation features using the TweetClaw tool. A review comment suggests refining the new entry to be more concise, ensuring it matches the brevity and style of the existing list items.

The new list item is significantly more detailed and longer than the existing items in the "Key capabilities" section. To maintain consistency and readability, consider phrasing it more concisely while still highlighting the tool and its core functions.

Suggested change

	- X/Twitter automation with [TweetClaw](https://github.com/Xquik-dev/tweetclaw) for tweet search, reply tracking, follower export, and approval-gated posting
	- X/Twitter automation via [TweetClaw](https://github.com/Xquik-dev/tweetclaw) (search, tracking, exports, and approval-gated posting)

Addressed the review by condensing the TweetClaw capability bullet to match the surrounding list style. Re-ran git diff --check and a targeted secret-pattern scan on the touched diff.
