Add usage-lead and usage-feature shortcodes to encapsulate the
alternating two-column layout, then migrate all ten usage pages
(cio, sysadmin, freelance, geek, devops — EN and FR) from raw
HTML files to plain Markdown using those shortcodes.
OG/Twitter tags now use page-specific titles and descriptions instead of
hardcoded site-wide defaults. Added canonical URLs, og:locale with
alternate languages, and unique titles/descriptions to all content pages
(use-case personas, community, press kit, about pages) in both EN and FR.
