feat: add shape-preserving line denoising

[brandtnewlabs]

Summary

• add opt-in LineConfig.simplify screen-space path simplification for LiveChart
• apply the shared setting to LiveChartSeries with per-series SeriesConfig.simplify overrides
• preserve original data for range fitting, live values, markers, and scrubbing
• reuse worklet scratch buffers and bound simplification ranges to keep per-frame cost predictable
• add focused unit and renderer coverage
• add a dedicated raw-vs-simplified example screen, guide, API documentation, navigation entry, and changelog entry

Why

Dense samples can produce a visually noisy Skia path even when the underlying trend is clear. Consumers need an opt-in way to remove small screen-space deviations while keeping meaningful peaks, valleys, timing, and all interaction values grounded in the original dataset.

API

<LiveChart
  data={data}
  value={value}
  line={{ simplify: 1 }}
/>

The tolerance is measured in screen pixels. 0 remains the default and preserves existing rendering.
