feat(blog): publish "How to Install Odoo Modules Using Git"

New post at blog/posts/how-to-install-odoo-modules-using-git.html
(2026-10-28, area "deep dive"), body pasted verbatim from the boss's
supplied block (7 h2, two figures in place). Chrome copied from the
newest post (odoo-community-is-going-online-on-odoo4projects.html:
main.blog-post / span.badge / div.post-meta / img.post-image /
div.post-body / a.back-link), style block trimmed to the rules this
page uses plus the ol/figure/figcaption rules its body needs.

Additive wiring: og:image + twitter:card, post-image after post-meta
(alt = h1), BlogPosting JSON-LD with dateModified.

blog/index.json gets the entry first (newest-first, key order
id,date,area,headline,teaser,link,image) by text splice - 15 -> 16
posts; sitemap.xml one new 0.6 blog url - 35 -> 36 <loc>; llms.txt one
new line at the top of the post list.
