feat(backend): rfdetr-cpp native object detection + segmentation backend (#10028)

Browse Source 
Adds a Go native gRPC backend that dlopens librfdetrcpp.so (built from
mudler/rf-detr.cpp at the pinned RFDETR_VERSION) via purego and exposes
the rfdetr.cpp inference pipeline through LocalAI's existing Detect RPC.

Supports all 5 RF-DETR detection variants (Nano/Small/Base/Medium/Large)
and 6 segmentation variants (SegNano/SegSmall/SegMedium/SegLarge/
SegXLarge/Seg2XLarge) with F32/F16/Q8_0/Q4_K quantizations. Pre-built
GGUFs ship at mudler/rfdetr-cpp-* on HuggingFace.

Detection returns Bbox + class_name + confidence; segmentation also
returns PNG-encoded per-detection masks via the rfdetr_capi accessor
functions (rfdetr_capi_get_detection_{class_id,box,score,class_name,
mask_png}).

End-to-end verified through POST /v1/detection: HTTP -> gRPC -> purego
dlopen -> rfdetr.cpp -> ggml -> response (9 detections on the detection
model, 21 detections + valid PNG masks on the seg-nano model against
the kitchen fixture).

Wiring:
  - backend/go/rfdetr-cpp/{main.go,gorfdetrcpp.go,CMakeLists.txt,
    Makefile,run.sh,package.sh,test.sh,.gitignore}
  - Top-level Makefile: BACKEND_RFDETR_CPP, docker-build target,
    .NOTPARALLEL, prepare-test-extra, test-extra
  - backend/go/rfdetr-cpp/Makefile: `test` target invoked by test-extra
  - .github/backend-matrix.yml: CPU + CUDA-12/13 + L4T CUDA-12/13
    (arm64) + HIP + Vulkan (amd64 + arm64) + SYCL f32/f16
  - backend/index.yaml: rfdetr-cpp meta anchor + latest/development
    image entries for every matrix tag-suffix
  - .github/workflows/bump_deps.yaml: RFDETR_VERSION pin tracking
    (mudler/rf-detr.cpp branch main)
  - gallery/index.yaml: 11 rfdetr-cpp-* entries (nano + 4 detection
    variants + 6 seg variants), all backed by mudler/rfdetr-cpp-*
    on HuggingFace with sha256 pinning on the F16 default
  - core/gallery/importers/rfdetr.go: GGUF auto-routing for HF imports
    (mudler/rfdetr-cpp-* repos route to rfdetr-cpp, Transformer-format
    repos stay on the Python rfdetr backend; explicit preferences.backend
    overrides both heuristics)
  - core/gallery/importers/rfdetr_test.go: table-driven coverage of the
    auto-routing + a live mudler/rfdetr-cpp-nano cross-check

scripts/changed-backends.js needs no change: the existing
Dockerfile.golang -> backend/go/${item.backend}/ branch already routes
the 9 rfdetr-cpp matrix entries to the correct backend path.
