…+ ggml-speech SVE fix) Bump the tts-cpp pin to 2026-06-26 (qvac-registry-vcpkg #214) and advance the default-registry baseline to that registry merge commit (162f8f7c). Brings two merged QVAC-20557 fixes into the tts-ggml addon: - tts-cpp 2026-06-26 = qvac-ext-lib-whisper.cpp master 586268bf (PR #67): run Chatterbox correctly on ARM Mali Vulkan via an is_arm_mali-gated unfused CFM attention (fixes the f32 flash_attn_ext miscompute that drove f0 to NaN and broke the audio). Zero change off ARM Mali; CPU output byte-identical. - ggml-speech 2026-06-26 = qvac-ext-ggml speech f5727c32 (PR #30): SVE ggml_vec_dot_f32 leftover-tail fix (svmad_f32_m -> svmla_f32_m), removing the ~12 kHz Nyquist tone on Tensor/Pixel CPU. Pulled in transitively because tts-cpp 2026-06-26 requires ggml-speech >= 2026-06-26. Resolves to tts-cpp@2026-06-26 -> ggml-speech@2026-06-26 (verified via vcpkg dry-run). Manifest-only; the throwaway validation overlays lived only on the ci-validate branch and are not part of this change. Version/CHANGELOG bump follows as a separate release PR.

…+ ggml-speech SVE fix) (#2905) * QVAC-20557 tts-ggml: consume tts-cpp 2026-06-26 (Chatterbox Mali GPU + ggml-speech SVE fix) Bump the tts-cpp pin to 2026-06-26 (qvac-registry-vcpkg #214) and advance the default-registry baseline to that registry merge commit (162f8f7c).

Manifest-only; the throwaway validation overlays lived only on the ci-validate branch and are not part of this change. Version/CHANGELOG bump follows as a separate release PR. * QVAC-20557 tts-ggml: enforce Chatterbox-on-Mali GPU in gpu-smoke (drop Chatterbox allowPolicyCpu) Chatterbox now runs on the ARM Mali Vulkan GPU (tts-cpp passes allow_arm_mali=true), so gpu-smoke + the KV-cache GPU tests no longer tolerate a Mali->CPU fallback: flip Chatterbox allowPolicyCpu true->false in gpu-smoke.test.js, kvCacheMatrix.js, and chatterbox-kv-cache-gpu.test.js so CI fails if Chatterbox silently falls back to CPU on Mali. Refresh the now-stale "allow_arm_mali=false / Mali declined" comments in those tests plus ChatterboxModel.cpp and BackendUtils.hpp. Test-strictness + docs only; no runtime change.
