Feature: Include Collections in Search results.

[Dream-World-Coder]

Right now only users & posts appear, show collections too.

This is already implemented! 🎉 \n\nCollections search is now available in the /search endpoint:\n- Search by title and description (case-insensitive, partial match)\n- Supports pagination (page, limit params)\n- Public collections only\n- Filter by type: ?type=collections or ?type=all\n\nExample: GET /search?q=javascript&type=collections&page=1&limit=100\n\nThe feature was added as part of the search pagination update. Closing this issue! ✅
