[BUG]: Mandrel releases such as java@23.1.12-mandrel no longer install, and java@21-mandrel installs Mandrel 23.1.8 #106

Version
vfox-java main (db38b70) and v0.6.2, vfox 1.0.13

OS
Linux

Describe the bug
Foojay now gives each Mandrel package the JDK major as java_version and keeps Mandrel's own number in distribution_version. The plugin names installs after java_version, so Mandrel's numbers no longer install, vfox search java mandrel lists one name per JDK major, and a bare major does not get the newest release:

$ vfox install java@23.1.12-mandrel
plugin [PreInstall] method error: ~/.vfox/plugin/java/hooks/pre_install.lua:41: No JDK found for 23.1.12-mandrel on linux/amd64. Please check available versions with 'vfox search java'

Download progress and the stack trace are trimmed. For JDK 21, Foojay lists 23.1.12.1 first, but a bare major asks with latest=available, and then Foojay answers with 23.1.8:

$ curl -s 'https://api.foojay.io/disco/v3.0/packages/jdks?version=21&distribution=mandrel&architecture=x64&archive_type=tar.gz&operating_system=linux&lib_c_type=glibc&directly_downloadable=true&latest=available' | jq -r '.result[] | [.java_version, .distribution_version, .filename] | @tsv'
21	23.1.8	mandrel-java21-linux-amd64-23.1.8.0-Final.tar.gz

My guess is that Foojay cannot tell which one is newest when every JDK 21 package has the same java_version. 25-mandrel gets 25.0.1.0 the same way, where 25.0.4.1 is out. 23-mandrel has changed meaning as well: it was Mandrel 23 and is now JDK 23, which is Mandrel 24.1.2. When v0.6.2 came out on 2026-10-18, Foojay listed Mandrel up to 24 under Mandrel's numbers and 25 under the JDK's, as the docs say:

Liberica NIK changed the other way. Its java_version is now the full JDK version for every release, so java@21-nik picks 21.0.12.1+2-nik, which is NIK 23.1.12.1 and the newest. What it lost is NIK's own numbers: java@23.1.8-nik fails with No JDK found, and 23-nik is now JDK 23, which is NIK 24.1.2.

Foojay accepts distribution_version as a query parameter, and with the same platform parameters distribution=mandrel&distribution_version=23.1.12.1 returns that one package. Naming Mandrel installs after distribution_version could bring Mandrel's numbers back, and a bare major would then have to find the newest distribution_version itself.

Also written for the old numbering: the comment in hooks/available.lua (L19-L22), the Mandrel and NIK ranges on Apple silicon in docs/platforms.md (L56), the 23.1.12-mandrel case and its comment in tests/pre_install_test.lua (L345-L354), and the same places in docs/zh-CN.

Found while adding the distributions in #104, and checked again while working on version-fox/vfox#390.
