whisper.cpp: add version 1.9.4

Worked ahead of SBo, which is still at 1.6.2. Upstream moved to
ggml-org/whisper.cpp; HOMEPAGE and DOWNLOAD follow it.

OpenVINO is required and always enabled. openvino installs under
/usr/share/openvino, off the default linker path, so cmake is pointed
at its config dir and its library dir goes into the install rpath,
which lets the binaries run without sourcing setupvars.sh. OpenBLAS
stays autodetected.

Built with static libs and shipped as binaries only: the bundled ggml
would otherwise install libggml*.so and ggml headers that clash with
llama.cpp-vulkan, the same approach as stable-diffusion.cpp-vulkan.

Test-built on -current with openvino as a local dep, lint clean. That
needs OpenCL-CLHPP 2026.05.29, which the buildsystem gets from a
slackrepo hint; SBo still ships 2024.05.08.

Adds the nvchecker stanza and README row.

+High-performance inference of OpenAI's Whisper automatic speech

+
+  - Plain C/C++ implementation without dependencies
+  - AVX intrinsics support for x86 architectures
+  - Mixed F16 / F32 precision
+  - Integer quantization support
+  - OpenVINO encoder support
+
+Installs whisper-cli, whisper-server, whisper-bench, whisper-quantize,
+whisper-vad-speech-segments, parakeet-cli and parakeet-quantize.
+
+OpenVINO support is built in. The encoder must be converted to OpenVINO
+IR format first, see "OpenVINO Support" in the bundled README.md.
+
+OpenBLAS is autodetected: if installed, it is used for the BLAS backend.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
