[BUG]: vfox install java@25-graal installs the GraalVM feature release 25.4.4.1-graal instead of the newest 25.0 LTS build #97

Version
vfox-java main (3b38e44), vfox 1.0.13

OS
Linux

Describe the bug
Since #74, a bare major installs the newest release of that major. For Oracle GraalVM 25 that is now a monthly feature release rather than a build of the 25.0 LTS line:

$ vfox install java@25-graal
Preinstalling java@25.4.4.1-graal...

Please use `vfox use java@25.4.4.1-graal` to use it.
$ vfox use --global java@25-graal

$ java -version
java version "25.0.4.1.1" 2026-08-18 LTS
Java(TM) SE Runtime Environment Oracle GraalVM 25.4.4.1.1+1.1 (build 25.0.4.1.1+1-LTS-jvmci-25.4-b23)
Java HotSpot(TM) 64-Bit Server VM Oracle GraalVM 25.4.4.1.1+1.1 (build 25.0.4.1.1+1-LTS-jvmci-25.4-b23, mixed mode, sharing)

java -version says LTS because the JDK underneath is 25.0.4.1.1, but the GraalVM release on top is 25.4, a feature release. v0.6.1 installs GA 25-graal instead. With latest=available, Foojay lists the feature releases first for version=25&distribution=graalvm (25.4.4.1, 25.3.4.1, 25.2.4, 25.1.3, 25.0.4.1, 25.0.4 on linux x64), and PreInstall takes the first one:

Oracle's own tools read "GraalVM 25" as the 25.0 line. https://download.oracle.com/graalvm/25/latest/graalvm-jdk-25_linux-x64_bin.tar.gz is 25.0.4 (its .sha256 is the same as for 25/archive/graalvm-jdk-25.0.4_linux-x64_bin.tar.gz), and graalvm/setup-graalvm downloads that URL for java-version: '25':

There, a feature release has to be asked for with version: '25.4' or 25i-latest:
https://github.com/graalvm/setup-graalvm/blob/f652a0efa63e76b0a69eac38011d6e27fbf7e1bf/README.md?plain=1#L214

Feature releases come out every month and each one supersedes the previous one (https://www.graalvm.org/release-calendar/), so anyone who installs 25-graal, a CI job for example, leaves the LTS line and gets a different feature release every month. For graal, skipping the packages whose second component is non-zero, the same check #95 needs, would make 25-graal take 25.0.4.1, the newest 25.0 build Foojay lists.

25-graalce takes 25.4.4.1-graalce too, but the 25.0 line of GraalVM Community Edition ended with 25.0.2 in January 2026, so for it the feature releases are the only ones still updated. This issue is about graal only.

Found while working on #64.
