Fix cookbook search to filter every card

[dprevoznik]

Summary

The search box on the cookbooks page only filtered cards whose link started with https://github.com/kernel/cookbooks/tree/main/. The other 11 cards link to internal guides, partner sites, or other repos, so they never hid. Searching for something that matches nothing still showed 11 cards and no "no cookbooks match" message.

This change:

• filters every .card inside the page's .columns sections, whatever it links to
• hides a section and its H2 heading when none of its cards match, so you don't get empty "Common patterns" / "Harnesses & models" headings

Testing

Ran mint dev locally and drove the page with headless Chromium:

query	before (prod)	after (local)
modal	13 cards	2 (Modal PR QA Agent, Modal Web Scraper)
captcha	11 cards	1 (Pausing for Captcha Solves)
vercel	13 cards	3
zzzz	11 cards, no empty message	0 cards, empty message, headings hidden
cleared	23	23

Note

Low Risk
Client-side DOM filtering only on the cookbooks page; no auth, data, or API changes.

Overview
Cookbook search no longer limits filtering to cards whose links point at the GitHub kernel/cookbooks tree. It now walks every .card under #content .columns, so internal guides and external links are included in match counts and visibility.

When a query hides every card in a section, that .columns block and its preceding H2 are hidden too, avoiding orphan section titles. The “no cookbooks match” state now reflects zero visible cards instead of leaving non-GitHub cards on screen.
