`fnode capi <entry.prg> -o libfivenode.dylib` generates all PRG as library
funcs + a cgo shim exporting the N-API C ABI, and builds buildmode=c-shared.
hb_bridge_handle_request stashes the request (read by PRG via FN_NAPI_REQ,
registered with HB_FUNC) and runs the PRG FN_HANDLE via capiVM.Run, returning
its JSON. capiEnsure calls RegisterLibModules so HB_FUNC/--rtl symbols install
into the VM (vm.Run drains libModules but not dynamicFuncs).
Verified: node → addon → Go libfivenode → PRG parses the request and runs
string/hash/JSON ops (Upper/Len/HB_ISHASH/hb_jsonDecode/Encode), round-trips a
200 response. Supersedes the P1 hand-written cmd/libfivenode (removed).
