QVAC-21928: CosyVoice3 native C++/ggml TTS engine (Qwen2 LM + DiT flow + CausalHiFT) #23

Workflow file for this run

.github/workflows/engines-cross-ci.yml at 87fcb68

	# Cross-platform lanes for the engines (engines/parakeet/, engines/tts/ —
	# moved from parakeet-cpp/, tts-cpp/ by the repo reorg QIP, PR 1).
	#
	# Complements parakeet-ci.yml / tts-ci.yml (linux+mac build+test):
	# - windows: full build + non-GPU ctest (MSVC, static ggml)
	# - android: compile smoke, arm64-v8a via NDK (no device to run tests on)
	# - ios: compile smoke, arm64 device slice, Metal embedded (flags
	# mirror build-xcframework.sh)
	# On-device e2e stays downstream in tetherto/qvac; these lanes exist to
	# catch cross-compile/link breaks before the registry pin chain.
