Add JavaFX bundled version support with -fx suffix

[Copilot]

Users cannot distinguish JDK versions bundled with JavaFX from standard versions. The foojay API provides a javafx_bundled field that was not being utilized.

Changes

• hooks/available.lua: Append -fx suffix to versions where javafx_bundled: true; show "JavaFX" in notes column
• lib/distribution_version.lua: Parse fx token from version strings (e.g., 21.0.5-zulu-fx) and expose javafx_bundled flag
• hooks/pre_install.lua: Filter JDK packages by JavaFX requirement to ensure correct package selection
• Documentation: Update both READMEs with usage examples

Usage

# Search shows -fx suffix for JavaFX versions
vfox search java zulu
# 21.0.5-zulu
# 21.0.5-zulu-fx    # JavaFX

# Install JavaFX bundled version
vfox install java@21.0.5-zulu-fx

<issue_description>通过版本号却分不出来，还是根本没有带fx的版本呢?
sdkman是可以的，刚切换到vfox，看来sdkman还不能弃用</issue_description>

<agent_instructions>foojay 里有字段可以区分的，lua 层需要解析后显示的时候处理一下，然后版本号里也可以加个 fx 来区分
是这个字段：
"javafx_bundled": true,</agent_instructions>

Updated in 04b4dc4. The -fx suffix is now placed after the distribution name (e.g., 21.0.5-zulu-fx instead of 21.0.5-fx-zulu) to match the convention used by other tools.
