* 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

* 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.
