* Handle cache restore promise rejections
Validate dependency cache providers before Java installation and settle cache restore failures immediately while preserving setup error precedence.

* Make cache-rejection regression test deterministic
Reject the cache restore only after it has started and while the Java
installation is still pending, instead of relying on event-loop timing.
Verified the test fails against the pre-fix implementation.

* Validate cache input after required input checks
Move the package-manager validation out of the top of run() so that
missing java-version/java-version-file and toolchain id errors keep
their original precedence. Validation now happens immediately before
the cache restore is started, which still fails fast before any JDK
download.
