Struct-returning methods now hand back a typed Go struct instead of the raw
CBOR/bytes. Since the native return POD is freed right after the callback, the
POD->Go conversion must happen in-callback: the generator emits a `fromC()`
reader per {.ffi.} type and, per struct-returning proc, an exported Go result
callback. The method calls the native entry point directly with that callback
and a `runtime/cgo.Handle` (boxed in a small C allocation so it travels through
the void* userData checkptr-safe), then blocks until the callback delivers the
typed value or error on the result slot.
String/raw-returning procs keep the existing C-bridge + condvar path. Validated
end-to-end (Echo/Complex/Schedule) including under `go run -race`.

Allows exposing Nim projects to other languages
Example
examples/timer is now a self-contained Nimble project that imports nim-ffi directly.
Use cd examples/timer && nimble install -y ../.. && nimble build to compile the example.
