Rename ShadowObjectParams to ShadowObjectCreationAPI

[Copilot]

Renames the ShadowObjectParams interface to ShadowObjectCreationAPI for clarity and consistency with the documented concept of the "Shadow Object Creation API."

Changes

• types.ts: Renamed interface and updated dependent types (ShadowObjectConstructor, ShadowObjectConstructorFunc)
• Test files: Updated imports and type references in Kernel.spec.ts and ShadowEnv.spec.ts
• README.md: Updated documentation, code examples, and section title
• CHANGELOG.md: Added entry for the rename (historical entries preserved)

Usage

import { ShadowObjectCreationAPI } from "@spearwolf/shadow-objects";

export function MyShadowObject({
  useProperty,
  createEffect,
  onDestroy
}: ShadowObjectCreationAPI) {
  // ...
}

Original prompt

Rename the ShadowObjectParams interface to ShadowObjectCreationAPI. Find all references in sources and documentation that refer to this interface and adjust the wording so that it always refers to the “Shadow Object Creation API.” Adjust the tests, documentation, and CHANGLOG accordingly.
(The exception here is the CHANGELOG: please do not transform the uses from history here, only document the new changes).
