refactor(backends): extract shared package-system-libs.sh from package.sh
The arch-detect-and-copy-system-libs block (Darwin rpath / x86_64 / aarch64
loader + libc/libstdc++/libgcc_s/libm/libgomp/libdl/librt/libpthread) was
inlined verbatim in 31 backend package.sh scripts. Extract it into a single
sourced scripts/build/package-system-libs.sh, the CPU-side counterpart to
scripts/build/package-gpu-libs.sh and its sourcing contract.
Consolidating the copies fixes three drift classes that had crept in:
- libgcc_s.so.1 and libstdc++.so.6 were listed twice in 9 backends
(acestep-cpp, crispasr, moss-tts-cpp, omnivoice-cpp, piper,
qwen3-tts-cpp, silero-vad, stablediffusion-ggml, whisper); the shared
script copies each once.
- libgomp.so.1 was omitted from opus. OpenMP consumers dlopen it rather
than link it, so the missing copy only failed at runtime; the shared
script always includes it.
- the Darwin @loader_path/lib rpath was applied only in piper and
silero-vad; both now pass their packaged binary to the shared script,
preserving that behavior. Every other backend passes an empty binary
path so no rpath is added, preserving its current behavior.
Each backend's pre/post packaging steps (binary copy, run.sh, ldd closure
walks, ggml variant bundling, espeak/OpenBLAS extras, the ds4 validate step)
are preserved verbatim; only the inline if/elif/else arch block is replaced
by a single source line.

* feat(backend): add moss-tts-cpp text-to-speech backend
Add a Go + purego backend wrapping the moss-tts.cpp ggml port of the OpenMOSS
MOSS-TTS-Local v1.5 text-to-speech model (GPT-J local transformer decoded through
MOSS-Audio-Tokenizer-v2), producing 48 kHz stereo audio with optional
reference-audio voice cloning. Mirrors the qwen3-tts-cpp backend: dlopen the
static-ggml shared library, bind the moss-tts.cpp C-API via purego, and serve
the gRPC TTS method. A thin C shim holds the pipeline handle and copies engine
PCM into a Go-freeable buffer.
Wires the CI registration: backend-matrix.yml (CPU, CUDA 12/13, Intel SYCL
f16/f32, Vulkan, ROCm, NVIDIA L4T, plus Darwin metal), backend/index.yaml metas
and image entries pointing at mudler/MOSS-TTS-Local-Transformer-v1.5-GGUF, the
root Makefile build targets, and the changed-backends.js path mapping.

* docs: list the moss-tts-cpp backend among the LocalAI-maintained engines
Add moss-tts.cpp to the README "Backends built by us" table, the
Text-to-Speech compatibility table, and the reference-audio voice-cloning
backend list, so the new backend is documented alongside its peers.

* backend(moss-tts-cpp): pin moss-tts.cpp to the squashed single-commit release
moss-tts.cpp history was collapsed to a single commit; repoint MOSSTTS_CPP_VERSION
to ee722b8e9205ee9b1b1c398a4e87e4e393e9be41.

* backend(moss-tts-cpp): add the moss-tts-cpp-development gallery meta
The gallery had the -development image entries but no matching -development
meta anchor (as locate-anything-cpp and depth-anything-cpp have), so the master
build was not installable as a gallery backend. Add moss-tts-cpp-development
mirroring the production meta with the -development capability image names.
