LyAhn a39ec536fd Improve CPU Inference Stability: Adaptive Buffering & Chunk Accumulation (#11)
* Improve CPU Inference Stability: Implement Adaptive Buffering and Chunk Accumulation

This change addresses audio stuttering issues when running on CPU-only hardware by:
- Implementing server-side audio chunk accumulation to reduce SSE overhead.
- Introducing device-aware default configurations for buffering and inference steps.
- Exposing key performance parameters as environment variables.
- Enabling the frontend to adaptively adjust its buffering thresholds based on the server's configuration.

Changes:
- Modified `server/vibevoice_server.py` to support accumulation and provide config via `/health`.
- Updated `web/hooks/useStreamingGeneration.ts` to accept configurable buffering parameters.
- Updated `web/app/page.tsx` to fetch and apply server-side configuration.

Verified on CPU mode in the development environment.

* Improve CPU Inference Stability: Adaptive Buffering UI & Logic

This change enhances the initial CPU stability fix by:
- Exposing adaptive buffering settings (Pre-buffer, Re-buffer Threshold, Resume Threshold) in a new "Advanced Buffering" UI section.
- Managing buffering settings in the application state to allow for manual overrides.
- Implementing robust re-initialization of buffering and inference defaults whenever the server's device (CPU/CUDA) changes.
- Including the active device in the server's config object for reliable client-side detection.

Verified with frontend screenshots and full build. Responds to PR feedback regarding actioning the adaptive logic.

* Refine adaptive buffering: env helpers, threshold validation, a11y fixes

- Extract _env_int/_env_float helpers in server to validate env-var config
  with graceful fallback instead of bare int/float casts
- Fix inference_steps falsy-check (0 is valid) to use explicit None guard
- Enforce rebufferThresholdSecs < resumeThresholdSecs in both the hook
  (with console.warn + clamp) and the GenerationControls UI (sliders block
  invalid states by auto-bumping or ignoring the drag)
- Add type="button", aria-expanded, aria-controls, htmlFor, and input id
  attributes to GenerationControls for accessibility
- Add .vscode/settings.json to .gitignore; sort package.json scripts
