NAP-218. The registry's `GET /` now serves the built web bundle from
`web/dist/` (embedded into the binary at compile time via rust-embed)
instead of the NAP-215 placeholder, and `GET /assets/*` serves the
hashed JS/CSS chunks Vite produces.
When `web/dist` is empty (fresh checkout without `pnpm build`), a
small fallback page tells the operator to run the JS build. That
keeps `cargo run -p maestro-registry` usable without a node
toolchain installed.
