feat(ci): add pre-release stage for feature branches

- Add pre-release job that runs on feature/* branches (not master)
- Update .releaserc.json to specifically match feature/* branches
- Prereleases strip 'feature/' prefix from version identifier
- Example: feature/foo creates 1.2.0-foo.1 on 'next' npm channel
