hbrtl_ext/napibridge reimplements the C++ fivenode TFNModule in Go: it calls
the addon's registered C callbacks (npmRequire/npmCall/npmMethods/npmEnd) over
cgo. FN_REQUIRE(module) gets a handle, enumerates its methods, and builds a PRG
object whose method closures proxy oObj:method(args) to Node; results decode as
scalar / native array|hash / nested object handle (e.g. Buffer). The capi shim
forwards tfn_register_callbacks -> napibridge.StoreCallbacks. Calls run on the
node main thread (sync handleRequest), so the direct tfn_npm_* path needs no
marshaling.
Verified end-to-end (node -> addon -> Go libfivenode -> PRG):
- builtin: oOs:hostname()/platform()/arch() -> real values; oOs:cpus() -> native
array, Len()=10.
- real npm: oQR:imageSync() on qr-image (which goja could NOT run) -> Buffer
handle -> :toString("utf8") -> valid 1138-byte SVG.
Full npm is now reachable in-process. P4 (async/Promise via worker + npmAwait)
remains for async methods like qrcode.toString.
