ci: add misc npm publish workflow (#11764)

kdy1 · web-flow · commit 236eff01dd30 · 2026-04-02T22:20:01.000+01:00
## Summary
- Add a new workflow named `Publish misc packages`.
- Support manual publishing of `@swc/types` and `@swc/helpers` via
`workflow_dispatch`.
- Add a branch guard so the workflow only runs from `main`.

## Details
- Add an `npmTag` input with `latest` and `nightly` options.
- Use a matrix strategy to publish both packages in parallel.
- Keep trusted publish settings with `id-token: write`, `environment:
publish`, and an npm upgrade step.
- Publish with `yarn npm publish --access public --tag ...
--tolerate-republish`.
