Added homepage blog surfacing and pagination updates on the website, while refining openclaw-container skills and bumping OpenClaw...

Added a "From the blog" section to the homepage, surfacing recent posts for visitors who land on the root URL.

Blog index now supports full pagination — page 1 is canonical at /blog/ and subsequent pages live at /blog/2/, /blog/3/, etc.

Refined skill packaging/layout (including new orchestration and tree skills, plus reorganized existing skill directories/scripts).

Bumped OpenClaw from 2026.2.19-2 to 2026.2.21-2 in Dockerfile; upstream v2026.2.21 introduced major provider/routing upgrades and stricter handling around secure config paths.
