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 Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: cc2c0256-c55e-4a35-a584-5bed7e8b11ad * 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 Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: cc2c0256-c55e-4a35-a584-5bed7e8b11ad * 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.
