v4.0.0

Added

• Added native ESM output alongside CJS [#367]
  • Published artifacts now live under dist/ instead of at the repo root; the main entry moved from react-plotly.js to ./dist/index.cjs
  • Dropped the unminified UMD bundle
  • import Plot from 'react-plotly.js' now resolves correctly in Rolldown and any other strict ESM environment
• Added TypeScript declaration files (index.d.ts / factory.d.ts) [#368]

Changed

• Update linting dependencies [#366]
• Refactored the wrapper from a class component to a functional component using hooks [#369]
  • Refs forwarded to <Plot> now resolve to the rendered <div> element (the plotly graph div) directly via forwardRef, instead of to the class instance
  • Migration: replace ref.current.el with ref.current

Fixed

• onPurge now fires and Plotly.purge runs on unmount [#372]
• Plot is re-initialized correctly after React StrictMode's dev-only simulated unmount/remount [#372]
• TypeScript declarations now expose ref forwarding so consumers can attach a typed ref prop without a TS error [#373]
