OpenWorkers: Self-Hosted Cloudflare Workers in Rust

Wrangler file format: not planned. We're taking a different approach for config but we intend to be compatible with Cloudflare adapters (SvelteKit, Astro, etc). Assets binding already has the same API. We just need to support _routes.json and add static file routing on top of workers, data model is ready for it.

For D1: our DB binding is Postgres-based, so the API differs slightly. Same idea, different backend.

Hono should just work, it just needs a manual build step and copy paste for now. We will soon host OpenWorkers dashboard and API (Hono) directly on the runner (just some plumbing to do at this point).

I think it would be worth it to keep the D1 compatibility, Sqlite and Postgres have different SQL dialects. Cloudflare has Hyperdrive to keep the connection alive to Postgres/other dbs, what D1/libSql/Turso brings to the table is the ability to run a read/write replica in the machine, this can dramatically reduce the latency.
