What
Adds RFC-0001: a proposal to expose the server startup orchestration as a public function on
extenddb-server, enabling external storage backends to produce runnable server binaries without forking.Why
External backend authors (TiDB #140, SQLite #109, community) currently must fork the repo to ship a server. The serve orchestration (AppState assembly, cache wiring, worker spawning) is private to the binary crate. This RFC proposes extracting it as a single
extenddb_server::serve()function so backends can depend on published crates instead of maintaining a fork.Testing done
Documentation-only PR — no code changes.
