Add Bluesky post parser (storage side)

Turn the Bluesky stub from grunt into a Post: escape the plain-text body,
keep line breaks, append the external link-card (dev logs almost always link
out to YouTube/Modrinth/the site), and add a View-on-Bluesky backlink.
Register the 'bluesky' posts-queue processor. Mirrors the Strapi parser.
