## Summary
- Support multiple Hugo release asset names for Linux, macOS, and
Windows so renamed upstream assets no longer fail with a plain 404.
- Preserve compatibility with legacy Hugo assets that used filename
forms such as `hugo_v0.20.3_*`, macOS `.zip` archives, and
`Linux_ARM`-style names.
- Add retry handling for missing candidate assets and macOS `.pkg`
extraction via `pkgutil --expand-full`, with focused URL and installer
tests plus the rebuilt `lib/index.js` bundle.
## References
- Fixes https://github.com/peaceiris/actions-hugo/issues/652
- `hugo-version: latest` still resolves through Homebrew; this change
does not fall back to an older Hugo version when the resolved release
has no compatible asset.
- Review note: `lib/index.js` is generated by `npm run build` and
contains bundled dependency code.
## Test plan
- [x] `RUNNER_TEMP=/tmp npm run all`
- [x] `npm run build`
