LyAhn 01ab3d1fc4 perf(cpu): tune streaming playback
Keep CPU async decode enabled without CFG parallelism, expand CPU buffering defaults for smooth playback, prevent CPU startup from mutating the lockfile during thread autodetection, and document runtime tuning variables in the example environment file.

LyAhn 75b84b211b perf: improve streaming generation pipeline
Add CUDA inference hot-path optimizations, safer attention fallback handling, and generation profiling hooks. Improve SSE streaming, browser buffering telemetry, and playback recovery while preserving default audio quality settings.

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
