ogmake API docs

Everything to add OG images to a site: the core API and signing docs, and a guide per framework for wiring the image URL into your own templates.

Core docs

• Quickstart — Sign your first request and render an image in minutes.
• Signing — The canonical-string and HMAC-SHA256 signing algorithm, in five languages.
• API reference — Every route, field, and error code, generated from the OpenAPI document.
• Public URLs — Unsigned image URLs for static sites with no runtime to sign a request.

Framework guides

• Django — Signed URL, computed in a view and passed to the template.
• Laravel — Signed URL from plain PHP, no Composer package required.
• Rails — Signed URL from a view helper, with Rails credentials and CSP notes.
• Hugo — Public URL from a head partial — no signing at build time.
• Jekyll — Public URL that works on GitHub Pages' sandboxed builds.
• Ghost — Public URL from a default.hbs Handlebars helper.
• WordPress — Public URL from a functions.php wp_head hook.
