v0.0.13

Removed

• The legacy root-level public/ folder (index.php, server.php, worker.php). The app now serves from site/public/ only.

Changed

• App::$public is now read from a public key in config.json, falling back to {path}/public, instead of always being hardcoded.
• Caddyfile worker and root paths updated to point at site/public directly.
