* feat(settings): compute-device override — auto | CUDA | ROCm | XPU | MPS | CPU

Auto-detect stays the default; the override kills the 'auto-detect picked
wrong' issue class. Applied at the single choke point (_probe()'s family
selection) so routing, get_best_device(), and every badge inherit it.
Resolution: OMNIVOICE_DEVICE env > Settings pick (prefs.json) > auto (#981
pattern). An override can steer, never invent hardware: a family the host
lacks is noted and ignored; cpu is always honorable. Applies at next
backend start (host caps are immutable per process — same restart contract
as the rest of the Performance tab, RestartBadge shown).

GET/PUT /api/settings/compute-device (admin-gated) reports resolved vs
applied so the panel shows restart-required truthfully and disables itself
under an env pin instead of pretending.

* fix(device-override): harvest — the override reaches CT2 ASR, full i18n, honest edge states

- _ctranslate2_cuda_ok() and the ASR sidecar now gate on the probe's family,
  so a cpu pin (or ROCm host) can never hand CTranslate2 a CUDA device —
  the override reaches every CT2 loader through one shared gate
- override_ignored exposed by the API and shown by the panel (env pin naming
  a device this machine lacks: auto is in effect, restart won't change it)
- all 8 panel strings + 5 device-family labels translated into all 21
  locales; failed saves keep their error visible through the re-sync
- test isolation: cleanup drops OMNIVOICE_DEVICE before re-probing so no
  overridden caps leak into later tests; panel tests wait for loaded state
- xpu/intel search keywords; oxfmt formatting

* fix(device-override): round 2 — fail-safe probe fallbacks, complete i18n, combined pin state

- a broken capability probe now means CPU everywhere (CT2 gate + ASR
  sidecar) — never a torch-derived guess that would bypass a cpu pin or
  re-open #1529 on ROCm; regression test added
- env-pinned AND not-detected shows both facts in one subtitle
- device_load_failed/perf_save_failed translated into all 21 locales;
  CJK/th/vi/ar strings no longer say literal 'Auto'
- test_ctranslate2_never_gets_cuda_on_a_rocm_build pins the probe family
  (it was order-dependent on the lru_cache before)

* fix(test): pin the probe family in the faster-whisper OOM-fallback test

Same class as the rocm-build test: it mocked torch but not the probe the
new override gate consults first, so on a cpu-family CI host the CUDA
fallback chain under test was unreachable.

React + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

React Compiler

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.

Expanding the ESLint configuration

If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the TS template for information on how to integrate TypeScript and typescript-eslint in your project.
