WebAssembly handler-runtime assembly (moved from the binary — node-library N2b).
Builds boatramp_server::HandlerRuntime from [handlers] config: the wasmtime
engine plus the libsql sql binding (single-node file per site, a cluster sqld
namespace, or an external Postgres/MySQL). Handlers-gated; a lean node gets a
disabled runtime. Lives here (not the backend-agnostic boatramp-server)
because it drives the concrete boatramp-storage SQL backends.
