* Self-installing stubs for optional API modules (export, flow, grid,

*
* Replaced by the real implementation when the matching resolver
* (exportApi(), flow(), grid(), regions(), category()) is imported and
* invoked. Until then, calling these chart methods surfaces an explicit
* import-guidance error instead of the generic `is not a function` TypeError.
*
* Imported for side-effect only from the ESM entry (src/index.esm.ts).
* UMD entry does not import this since it auto-installs the real APIs.
