c5c57508b3 fix(device): fall back to CPU when the GPU arch is unsupported, not 500 every generate (#756) (#757)
* fix(settings): contain + tighten the whole Settings surface (measure cap, container-query stacking, wrap the shared rows)

Two systemic issues drove 'too spread out' + 'elements go out of view' across
many Settings pages:

1. Spread — .settings-content capped at 1280px, so on wide windows every
   label-left/control-right row left a huge void. Introduce a --settings-measure
   token (720px, macOS-like) + --settings-rail, and cap the content to it,
   left-aligned under the nav. One token now controls the reading width.

2. Overflow + bad responsiveness — the row stack break was a *viewport* media
   query (560px), but the 168px nav rail means a 760px-viewport window only has
   ~530px of content, so rows went side-by-side in a cramped box. Make
   .settings-content a container (container-type: inline-size) and stack on the
   CONTENT width via @container, keeping the viewport @media as a fallback for
   the .st-row instances used outside Settings (Splash/FirstRun/Dub/SetupWizard).

3. The shared .perfpanel__row (button/badge row reused by 6+ panels:
   RemoteBackend, HFMirror, LLMEndpoint, Pronunciation, MCPBindings, …) was an
   inline-flex with no wrap and no max-width, so it ran off the right edge —
   add flex-wrap + max-width:100% + min-width:0. Plus two rigid-width fixes that
   escaped the row cap: ApiKeys input min-width:220→0, Appearance scale floor.

Frontend builds clean; tokens, @container query, and the wrap all verified in the
emitted CSS bundle.

* fix(settings): center the settings block + tighten measure (kill the lopsided right void)

The capped content was left-aligned, so on a wide window everything jammed to the
left with a dead empty third on the right (screenshot). Center the whole settings
block (nav rail + content) as a unit via max-width + margin-inline:auto, and drop
the measure 720→660 so label→control rows read denser. The cap is computed from
the tokens (rail + gap + measure + page padding) so the content track lands
exactly at --settings-measure.

* fix(device): fall back to CPU when the GPU arch is unsupported, instead of 500-ing every generate (#756)

get_best_device() called check_device_compatibility() and, on an unsupported
compute capability, only LOGGED a warning then still returned 'cuda' — so the
model loaded on a GPU whose kernels can't launch and every generate 500'd with
'CUDA error: no kernel image is available for execution'. Both a too-old card
(Pascal sm_61, GTX 10-series) and a too-new one (Blackwell sm_120 on pre-cu128
wheels) hit this.

Now an unsupported arch falls back to CPU (works, just slower) with a clear
warning; OMNIVOICE_FORCE_CUDA=1 overrides. Belt-and-suspenders: _oom_friendly_reraise
classifies a raw 'no kernel image is available' as an unsupported-GPU error
(switch to CPU / install matching torch) rather than the OOM/Flush message.

Tests: get_best_device → cpu on incompatible, stays cuda on compatible, honors
the force override; reraise gives the actionable GPU message, not OOM.

* test(device): patch detect_host_caps via string path so the #756 fallback test is full-suite robust

The first version aliased the import + inserted backend on sys.path, which patched
a module copy get_best_device's local 'from core.device_caps import detect_host_caps'
didn't resolve in the full suite (passed alone, failed in CI). Use the string-form
monkeypatch target; verified passing alongside the other device/model tests.

* docs(changelog): fold #757 device-fallback entry into [0.3.8]; drop the merge's stale [Unreleased] dupe
