dtrentin 73bbd9ddec feat(chart-realtime): v0.3.0 — dirty flag render, targetFps=30, iOS targets, KDoc, README

- Dirty-flag render: dataVersion counter in RealtimeChartState, skip Canvas draw
  when no new data since last frame (zero GPU work when sensor idle)
- targetFps=30 default in ChartConfig (pass null for max display refresh rate)
- iOS targets: iosX64, iosArm64, iosSimulatorArm64 + Platform.ios.kt actual
- KDoc: RealtimeChart params, dataVersion, ChartConfig.targetFps, LodMode entries,
  AxisLabelMode entries
- README: fixed Maven coords, added LoD/AxisLabels/Material3 sections, updated
  feature list and performance notes
- Tests: RealtimeChartStateTest (17 tests, dataVersion + signal lifecycle)
