- Added repeatable `--tag` argument parsing in `gen-npm-packages.ts` and threaded parsed tags into `generateNpmPackages` for targeted leaf publishing.
- Exported `prepareNativeCorePackage` and expanded package manifest typing to support scripted manifest rewrites used by release workflows.
- Reworked install-test smoke logic to pack the host leaf package, pack the rewritten natives core, and assert the platform leaf package resolves from the core optional dependency.
- CI now enabled OIDC publishing in the build matrix, installed Node 24/npm, and added a per-target native addon publish step.
- The release script now accepts `--native-leaf <tag>` and publishes only the matching generated native leaf package.
- Native package generation gained optional tag filtering with validation of requested leaf tags for targeted release publishing.
- Added `gen-npm-packages.ts` script to generate per-platform leaf packages under `npm/-/`.
- Updated CI release publisher to generate and publish leaf packages before rewriting the core manifest with pinned `optionalDependencies`.
- Core package now ships only JS loader and declarations; installs fetch only the host platform's `.node` binary.
