* fix(parakeet-cpp): darwin/metal support (libparakeet.dylib + DYLD path)
The parakeet-cpp backend had no macOS support and panicked at startup on
Apple/Metal nodes when purego.Dlopen could not find "libparakeet.so".
Fix it across the same four layers the sibling voxtral backend already
handles correctly:
- main.go: default the dlopen target to libparakeet.dylib on darwin
(runtime.GOOS), libparakeet.so elsewhere; PARAKEET_LIBRARY still wins.
- Makefile: also stage the built libparakeet.dylib next to the Go sources.
- package.sh: accept either the Linux .so[.X.Y] or the macOS .dylib when
bundling instead of hard-failing when no .so is present (the macOS case);
note that on Darwin only system frameworks are linked.
- run.sh: on Darwin set DYLD_LIBRARY_PATH and PARAKEET_LIBRARY to the
packaged .dylib; keep LD_LIBRARY_PATH + .so on Linux.
Mirrors backend/go/voxtral.

* fix(backends): darwin/metal support across purego Go backends
The parakeet-cpp fix in the previous commit was an instance of a bug
shared by nearly every purego/dlopen Go backend: the dlopen target was
hardcoded to a .so name and run.sh exported only LD_LIBRARY_PATH, so the
backend panicked at startup on macOS/Apple-Metal nodes (dyld needs the
.dylib name and DYLD_LIBRARY_PATH). voxtral was the only backend handling
this correctly.
Apply the same four-layer fix (mirroring backend/go/voxtral) to the
remaining affected backends:
whisper, sherpa-onnx, ced, stablediffusion-ggml, vibevoice-cpp,
qwen3-tts-cpp, omnivoice-cpp, crispasr, acestep-cpp, locate-anything-cpp,
depth-anything-cpp, rfdetr-cpp, sam3-cpp, localvqe
Per backend:
- main.go (sherpa-onnx: backend.go, two libraries): default the dlopen
target to the .dylib on darwin (runtime.GOOS), .so elsewhere; the
existing <BACKEND>_LIBRARY env override still wins.
- run.sh: on Darwin set DYLD_LIBRARY_PATH and point <BACKEND>_LIBRARY at
the packaged .dylib; keep LD_LIBRARY_PATH + the Linux CPU-variant
(avx/avx2/avx512) selection unchanged in the else branch.
- package.sh: also bundle the .dylib and stop hard-failing when no .so is
present (the macOS case).
- Makefile: also stage the built .dylib.
Notes:
- stablediffusion-ggml and acestep-cpp build their lib as a CMake MODULE,
which emits .so (not .dylib) on macOS; run.sh prefers .dylib and falls
back to .so so both layouts work.
- sherpa-onnx was already partly darwin-aware (Makefile/package.sh); only
run.sh and the two dlopen defaults needed fixing.
Linux behavior is unchanged. Verified gofmt-clean and
`CGO_ENABLED=0 go build` for every backend.

The qwen3-tts.cpp backend honored the request `language` field only via exact lowercase two-letter codes in the C++ language_to_id table, silently defaulting to English for anything else (en-US, EN, english, ...).
Add normalizeLanguage() in the Go handler: lowercase + trim, strip the region/locale suffix (en-US, pt_BR, zh-Hans -> en/pt/zh), and resolve common English full names (english -> en). The canonical codes match the existing C++ table, so no C++ change is needed. Covered by a pure-Go Ginkgo spec. Also document the language field and accepted forms under the Qwen3-TTS docs.
