Nginx site metadata (simai)

Simai-managed nginx site configs carry a canonical metadata header that acts as the single source of truth for admin operations (list/remove/doctor/set-php/ssl). The block must be placed at the top of each site config and uses simple # simai-* markers.

Required keys (metadata v2):

• # simai-managed: yes
• # simai-meta-version: 2
• # simai-domain: <domain>
• # simai-slug: <safe_slug>
• # simai-profile: <profile_id>
• # simai-root: </home/simai/www/<domain>>
• # simai-project: <safe_project_name>
• # simai-php: <8.1|8.2|8.3|none>
• # simai-ssl: <none|letsencrypt|custom|unknown>
• # simai-public-dir: <relative docroot or empty/"." for project root>
• # simai-updated-at: <YYYY-MM-DD>

Notes:

• Keep the block together near the file start, followed by a blank line before server{} content.
• All site creation/updates must write or update this block; admin tooling parses it to avoid drift.
• Future versions may extend keys; metadata version is explicit to allow migration.
