feat(site): surface ecosystem repositories on homepage

[LauraGPT]

Summary

• complete the approved product-hub homepage plan with a bilingual ecosystem adoption band
• route Fun-ASR, SenseVoice, and FunClip entry points through the existing fixed /go/* attribution endpoints
• keep the surface dense and responsive: three unframed columns on desktop and one column on mobile

Why

The approved Option A implementation plan calls for verified ecosystem references on the homepage, but the current page moves directly from production responsibilities to the final CTA. The production conversion log currently contains two non-smoke repository redirects, one each for Fun-ASR and SenseVoice, and none for FunClip. This change creates a measurable homepage path without hard-coding unstable star counts or changing redirect targets.

Validation

• red-first homepage contract reproduced the missing bilingual ecosystem section
• 51 product-site Python tests passed
• 21 product pages built and all 92 generated pages validated
• 7 Playwright checks passed at 390x844, 768x1024, 1440x900, and 1920x1080
• full-page screenshots inspected at mobile and desktop widths; no overflow, control overlap, or layout shift
• git diff --check passed
