feat(esm): tree-shakable grid, regions, category modules

* feat(esm): make export and flow APIs tree-shakable

- Introduce exportApi() and flow() module functions for opt-in ESM import
- Remove apiExport from Chart core and apiFlow from axis resolver
- Add stubs on Chart.prototype with logError for missing module guidance
- UMD bundle auto-includes both via index.ts
- Optimize isStackingRadiusData from O(n²) to O(n) pre-computed Set
- Add ESM tests for optional module loading behavior

BREAKING CHANGE: chart.export() and chart.flow() are no longer
included automatically in the ESM build. Explicit import required:

  import bb, { bar, exportApi, flow } from "billboard.js";
  bb.generate({ ...bar(), ...exportApi(), ...flow(), data: { ... } });

UMD bundle users are not affected.

* refactor(esm): remove prototype stubs for export and flow modules

Remove the stub implementations and delete calls that were added as
fallbacks — they are unnecessary now that the resolver pattern handles
lazy loading directly without stub cleanup.

* feat(esm): make grid, regions, category APIs tree-shakable

- Introduce grid(), regions(), category() resolver modules for opt-in ESM import
- Remove apiGrid, apiRegion, apiCategory from axis resolver
- Remove internal grid/region renderers from axis resolver
- Extend Chart/api/stubs with xgrids/ygrids/regions/category/categories stubs
- Add optional chaining in redraw/eventrect/flow/ChartInternal for grid/region methods
- Update UMD entry to auto-invoke new resolvers
- Update ESM entry to export new resolvers
- Point runtime error docs to new MODULE_IMPORTS.md guide
- Add tests for new optional modules

Add CHANGELOG-v4.md for release notes and MODULE_IMPORTS.md as the
canonical module import guide referenced from runtime error messages.

BREAKING CHANGE: In ESM builds, chart.xgrids()/ygrids(), chart.regions(),
chart.category()/categories() now require explicit import:

  import bb, {bar, grid, regions, category} from "billbo... (continued)
