ffiNewReq derived the request id with `let typeStr = $T`, allocating a
Nim GC string on the *calling* thread for every request. Embedded in a
foreign host (e.g. Go) the callers are transient, concurrent OS threads;
running Nim's GC there corrupts the heap under load. The type name is
known at compile time, so emit it as a `cstring` literal (the same value
already used as the registry key) — no runtime allocation. Applies to
both the {.ffi.} and {.ffiCtor.} request builders.
