* feat(proto): add speaker field to TranscriptSegment for diarization
Add speaker field to the gRPC TranscriptSegment message and map it
through the Go schema, enabling backends to return speaker labels.

* feat(whisperx): add whisperx backend for transcription with diarization
Add Python gRPC backend using WhisperX for speech-to-text with
word-level timestamps, forced alignment, and speaker diarization
via pyannote-audio when HF_TOKEN is provided.

* fix(whisperx): unpin torch versions and use CPU index for cpu requirements
Address review feedback:
- Use --extra-index-url for CPU torch wheels to reduce size
- Remove torch version pins, let uv resolve compatible versions

Signed-off-by: eureka928 <meobius123@gmail.com>
* fix(whisperx): pin torch CPU variant to fix uv resolution failure
Pin torch==2.8.0+cpu so uv resolves the CPU wheel from the extra
index instead of picking torch==2.8.0+cu128 from PyPI, which pulls
unresolvable CUDA dependencies.

* fix(whisperx): use unsafe-best-match index strategy to fix uv resolution failure
uv's default first-match strategy finds torch on PyPI before checking
the extra index, causing it to pick torch==2.8.0+cu128 instead of the
CPU variant. This makes whisperx's transitive torch dependency
unresolvable. Using unsafe-best-match lets uv consider all indexes.

* fix(whisperx): drop +cpu local version suffix to fix uv resolution failure
PEP 440 ==2.8.0 matches 2.8.0+cpu from the extra index, avoiding the
issue where uv cannot locate an explicit +cpu local version specifier.
This aligns with the pattern used by all other CPU backends.

* fix(backends): drop +rocm local version suffixes from hipblas requirements to fix uv resolution
uv cannot resolve PEP 440 local version specifiers (e.g. +rocm6.4,
+rocm6.3) in pinned requirements. The --extra-index-url already points
to the correct ROCm wheel index and --index-strategy unsafe-best-match
(set in libbackend.sh) ensures the ROCm variant is preferred.
Applies the same fix as 7f5d72e8 (which resolved this for +cpu) across
all 14 hipblas requirements files.

* revert: scope hipblas suffix fix to whisperx only
Reverts changes to non-whisperx hipblas requirements files per
maintainer review — other backends are building fine with the +rocm
local version suffix.

Some datacenter setups might be stuck with the 5.x kernel which doesn't
play well with CUDA >=12.9. To incrase compatibility with the CUDA 12.x
branch, downgrade to 12.8. For newer systems, it is still suggested to
use CUDA 13.x wherever compatible.

Qwen3 4b was using the wrong function format (i.e. using "function"
instead of "name") within the realtime API.
If we specify the function calling format explicitly then it stops it.
