Make native module loading robust and switch to prebuilds-only install

- Loader prefers a local build/Release build (dev), then static
  per-platform prebuild paths incl. darwin-x64/win32-x64, and falls
  back to node-gyp-build with a clear error on unsupported platforms;
  a missing or ABI-incompatible prebuild no longer crashes require()
- Drop the install script: the published package has no sources, so
  node-gyp fallback could only ever fail; move node-addon-api to
  devDependencies and declare engines.node >=14.17
- Remove redundant .npmignore (files field wins); anchor the version
  tag regex in prepublish.ts
