  - feat: Upgrade to angular 19
  - **BREAKING CHANGES**:
    - According to [issue #443](https://github.com/xieziyu/ngx-echarts/issues/437), we cannot import from `echarts/index.js` using Angular 19. Therefore, we need to perform a custom build and import everything required from `echarts/core`, `echarts/charts`, `echarts/components`, or other specific entry points.
    - `provideEcharts` is REMOVED.

    - `NgxEchartsCoreModule` is removed.
    - `[detectEventChanges]` is removed.
