Optimize Temurin tool-cache fast path with lazy loading (#1179)

* Optimize Temurin tool-cache fast path

- Lazy-load distribution installers so only the selected distro module is initialized
- Defer cache feature/cache module loading until cache input is provided
- Start cache restore early and await it safely alongside Java setup flow
- Update orchestration and lazy-loading tests; regenerate dist artifacts

* Address PR review comments

- Lazy-load cache save in cleanup path so no-cache runs avoid cache module init in post action
- Stage dist/setup/package.json in release script for chunked setup bundle completeness

* Fix CodeQL comment tag filter finding

Patch is-unsafe's XML comment-close detector during builds so generated bundles recognize both HTML comment end forms and satisfy CodeQL until the dependency publishes a fix.
