Build Backend Framework

[diamondburned]

Currently, libdb.so is a strictly frontend-only, backed only by a lightweight file server for serving the file system. The file system itself defines a very simple read-only file system:

GET /_fs.json
GET /_fs/{path}

Instead, we should build libdb.so on top of a proper Go backend. This will allow us to do really interesting stuff, such as:

• Tracking view counts and click counts
• Make public APIs for small and fun stuff, such as color-changing bars, message-of-the-days, etc.
• Have an entire chat/message room!
• GitHub redirection (currently this is done as a Caddy hack)
• Third-party asset CDN to prevent IP scraping

and much more!

We could also consider adding more Caddy hacks :)
